What is the most expensive metal in the world

The most expensive metals in the world - Top 10

As you know, metals are a group of chemical elements that have certain characteristics: high electrical and thermal conductivity, malleability, characteristic luster and some other properties. Man has learned to use metals for his own purposes almost from the very beginning of civilization.

Now it is very difficult to imagine any branch of human activity where chemical elements of this group would not be used. With the development of technology, humanity is identifying and creating more and more rare and very expensive metals. The price per gram for some of their types is really surprising.

Naturally, the question arises, what is the most expensive metal in the world at the moment?

There are two types of metals:

1. natural;
2. artificial (obtained in laboratory conditions).

Moreover, prices for the latter can be truly astronomical. In our article, we have selected the most expensive metals, regardless of their origin. So let's get started.

10. Silver / Ag (~ 0.5 USD per 1 gram)

Our top 10 opens with silver, called argentum in Latin. Silver has been known to mankind since ancient times because it can be found in nature in the form of nuggets, and it does not require any chemical processes to obtain. The metallic color itself is named after Argentum - silver.

Silver is a noble metal with a melting point of 962 degrees Celsius. It has the highest thermal conductivity of all known metals. It is widely used in the production of electrical engineering and electrical equipment, jewelry, and is included in the composition of various high-tech alloys used in a wide variety of areas of human activity.

Silver has long been known for its antibacterial properties; it can be used to destroy about 700 types of different bacteria.

Even on space stations, all water is purified with silver, and some housewives throw silver coins into milk to extend its shelf life.

9. Ruthenium / Ru (~ 2 USD per 1 gram)

Next on our list is ruthenium. Translated from Latin, its name means Russia or Rus'. And this is not surprising, because this chemical element was first discovered by chemist Klaus Karl from Kazan University in 1844.

Ruthenium is mined from platinum group metal ores and has similar physical properties to them. Also, a considerable amount of ruthenium is extracted from fission fragments of nuclear materials: plutonium and uranium.

Its melting point is 2334 degrees Celsius, making ruthenium a refractory metal. In its pure form, this chemical element is not used so often; it is mainly part of various alloys that are used in many areas of human activity. There are a number of isotopes of ruthenium that are produced as a result of radioactive reactions. For example, ruthenium 106, which is used in the treatment of cancer.

8. Scandium / Sc (~ 3-4 USD per 1 gram)

Our top continues with the most expensive rare earth metal - scandium. It got its name from the Scandinavian peninsula where it was discovered by Swedish scientist Lars Nilsson in 1879. Scandium is a light, silvery metal with a slight yellow tint.

The melting point of this chemical element is 1541 degrees Celsius. It is obtained by processing many ores.

Scandium is widely used in various fields of human activity: medicine (creation of the most advanced dentures), electronics (production of super-computers), nuclear energy, creation of solar panels, metallurgy (production of super-strong alloys) and much more.

The largest reserves of scandium-rich minerals are found in Norway and Madagascar. However, the largest producers of this metal are Russia and China.

7. Rhenium / Re (~ 4-7 USD per 1 gram)

In seventh place on our list is Renius. It is one of the rarest natural chemical elements on Earth. It was discovered in 1925 in Germany by two chemist spouses named Noddack. This metal has a characteristic shiny silver color.

Rhenium is extracted mainly from molybdenum concentrates. To obtain just 100 grams of rhenium, you will need to spend approximately 200 tons of copper and molybdenum ore. Its melting point is 3459 degrees Celsius. In terms of refractoriness, it is second only to tungsten.

The largest deposit of Rhenium and at the same time the producer is the country of Chile, also the leading countries are the USA and Russia. The refractoriness of this metal is of great interest in various fields. Rhenium is used in electronics, medicine, metallurgy, and is used as a catalyst.

Rhenium is the rarest natural metal on our planet.

6. Palladium / Pd (~ 19 USD per 1 gram)

Next on our list of the 10 most expensive metals is palladium. It was discovered by chemist William Wollaston in 1803, who was able to isolate the element from platinum ore. Palladium indirectly received its name in honor of one of the most revered goddesses in the myths of ancient Greece, Pallas Athena.

Palladium is a heavy metal with a silvery tint. Its production occurs as a result of the processing of several ores: copper, nickel and silver. The melting point of palladium is 1555 degrees Celsius.

The largest deposits of this chemical element are in Russia, which is also the largest supplier of palladium in the world. This metal is used in the engineering industry (automotive catalysts), jewelry, medicine, electronics, and the production of high-precision instruments.

Palladium is a generally recognized precious metal, traded on world exchanges. Most of the medals awarded to outstanding scientists and athletes are made from it.

5. Rhodium / Rh (~ 27 USD per 1 gram)

Fifth place on our list is Rhodium. Its melting point is 1966 degrees Celsius. Rhodium has a characteristic silvery luster and is a hard metal. The main countries producing rhodium are South Africa and Canada, but the mineral resources of Russia are also rich in it.

This metal is mainly used as a catalyst in many industrial fields; rhodium is also actively used in jewelry, improving the mechanical properties of precious metals by rhodium treatment and giving them additional shine.

The total amount of rhodium mined per year does not exceed several tens of tons.

4. Platinum / (~ 30 USD per 1 gram)

Despite the fact that platinum has long been valued more than gold, in recent years this precious metal has lost its position a little and let gold pass ahead. The first recorded mentions of platinum were associated with the conquistadors, who found it among the indigenous tribes of South America. Before the value of platinum was universally recognized, counterfeiters often diluted it with gold to create alloys. Now such coins are of great value to collectors.

The name of this chemical element is translated from Latin as a diminutive form of the word silver. The melting point of platinum is 2041.4 degrees Celsius, clearly indicating refractoriness. Main production countries: South Africa, the United States of America, Russia and Zimbabwe. Platinum, its alloys and derivatives are actively used in medicine, the production of high-tech and high-precision equipment, and jewelry.

The largest platinum nugget in history was discovered in 1843 in Russia in the Urals. It was named “Russia” and its weight was as much as 9 kilograms 635 grams.

Unfortunately, this giant has not survived to this day and was melted down.

3. Iridium / Ir (~ 35 USD per 1 gram)

Iridium opens the top three on our list. It has a melting point of 2466 degrees Celsius and is considered a refractory metal. Iridium has a characteristic white-silver color. This metal earned its name due to the variety of colors of its salts and is translated from ancient Greek as rainbow.

Pure iridium is very fragile and does not tolerate any mechanical treatment. The world's largest reserves are located in the depths of Russia, Canada and South Africa. A little over 2 tons of iridium are mined worldwide per year. Nuclear isomers of this metal are used as a source of electricity, and iridium can be found in fountain ink pens, engine spark plugs, glass blowing mouthpieces, and many other manufacturing applications.

2. Gold / Au (~ 40 USD per 1 gram)

If you ask what is the most expensive precious metal in the world, most people will name gold. Indeed, aurum, as it is called in Latin, is one of the most famous precious metals on planet Earth. In its pure form, gold has a yellow color without red impurities. Its melting point is 1064.18 degrees Celsius.

Gold mining began back in the Bronze Age, so it is not possible to name the discoverer of this treasure of the Earth’s bowels. The undisputed leaders in gold production are China, Australia, the USA and Russia. It is actively used in electronic manufacturing, dentistry, jewelry, in the production of ultra-precision instruments and the food industry.

The flexibility of gold is well known; it can even be used to create threads for sewing clothes. One hundred grams of gold can be stretched over approximately 282 kilometers.

One of the largest gold nuggets weighing about 73 kilograms was found in 1869 in Australia. It is noteworthy that it was only a few centimeters underground.

1. Isotope Osmium 187 (~ 10,000 - 200,000 USD per 1 gram) and California / Cf (~ 27,000,000 USD per 1 gram)

In the first place we have placed two metals obtained in laboratory conditions, the price for which stands out sharply from the rest of the list: the isotopes osmium 187 and californium 252.

Osmium 187

The only producer of the 187 isotope of osmium in the world at the moment is Kazakhstan. Its main valuable properties include incredible hardness and chemical passivity in contact with aggressive substances. Osmium is considered the hardest among all simple (consisting of atoms of one element) substances on Earth. The main areas of application of osmium 187 are medicine and aerospace production.

California 252

Californium 252 was obtained as a result of a nuclear reaction carried out in 1950 in California (hence its name) in the United States of America by a scientist named Seaborg. This isotope has fantastic energy obtained from the fission of atoms. The power of a gram of this chemical element is comparable to the power of one nuclear reactor. Californian 252 is produced in only two places on our planet:

1. Oak Ridge National Laboratory, USA.
2. Dimitrovgrad, Russia.

California 252 has the amazing property of emitting neutrons, with the help of which they determine deposits of various minerals, illuminate various hard-to-reach places, and look for microdamages in high-tech equipment. This metal is also used in the treatment of cancer. This astronomical cost is due to the complexity of the process of creating this metal; at the moment, no more than 9 grams of Californian have been created.

Our article has come to an end and now you know what the most expensive metal in the world is. Since metals market prices are so volatile, don't be surprised if some of our top 10 rankings change over time.

10 most expensive metals in the world

Our planet is rich in various types of minerals. The most valuable and practical of them are, of course, metals. Each of them is unique in its structure, composition and appearance. Specialists will separate all metals into natural and artificially derived ones. Paradoxically, artificial materials are many times more expensive than natural ones. This is explained, first of all, by the complexity of the technological process of their manufacture.

Today we propose to find out the top 10 most expensive metals in the world , the price per gram is given in US dollars as of 2018.

10. Scandium – $3-4

Scandium, being one of the most high-strength metals on Earth, has found wide application in various industrial fields: it is used in robotics, the construction of innovative technology (for example, laser), space and aircraft.

It has not bypassed the sports sphere either - the highest quality and most expensive equipment for golf, hockey and cycling is made exclusively from scandium. Speaking of the name: this metal was first discovered in the 19th century by Swedish chemist Lars Nilsson, who named his discovery after Scandinavia.

The cost of one gram of such metal is about 3-4 US dollars.

10 most expensive metals and their prices

Metals as chemical elements have a number of specific characteristics. For example, heat and electrical conductivity, malleability. Since the emergence of civilization, this natural resource has been widely used in many areas of life. In the 21st century, it is impossible to imagine industry, science, medicine, production of goods and everyday life in general without metals.

10. Silver

It is not only a beautiful metal, but also useful. Since ancient times, silver has been used for purification. It has been proven that up to 700 bacteria are destroyed with Argentum. Due to its antibacterial properties, silver is used to filter water at orbital stations. In everyday life, silver jewelry is worn not only by fans of the aesthetically beautiful metal, but also by superstitious people. In the mythology of many countries, silver protects against evil spirits.

Noble metal is easy to find in nature. Due to its high thermal conductivity, argentum is widely used in the production of electrical goods. And its hypoallergenic nature allows jewelry to shine even for those who are intolerant to precious metals, such as gold. This is the cheapest representative in this rating, because buy 1g. You can get silver for half a dollar.

9. Ruthenium

In ninth place in the TOP is the metal Ruthenium. If you translate the name into Russian, the metal is called “Rus”. And this is justified, because the place of discovery of the element is in Kazan. Ruthenium is extracted from large volume metal ores. For example, a significant proportion of the metal is contained in fragments of plutonium and uranium. Ruthenium is refractory. Softening requires heating to 2334° C. The use of ruthenium is extensive, but most often the metal acts as a component for subsequent useful alloys.

 Ruthenium isotopes are used in the treatment of oncology, as well as for the manufacture of laboratory equipment.

In European countries and Japan, the lion's share of the mined metal is used to create electronic circuits and circuits. It is difficult to imagine a chemical laboratory without ruthenium, since element No. 44 acts as a powerful catalyst in a number of reactions. Ruthenium production is concentrated in the Republic of South Africa. Cost 1g. is $2.

8. Scandium

A particularly strong element was discovered on the Scandinavian peninsula, hence the name. Metal melts at a temperature of 1541 degrees. The discoverer is Lars Nils. A Swedish scientist invented chemical element No. 21 in a related process for refining ore metals. In dentistry, it is difficult to imagine modern prosthetics without scandium.

What happens if you inhale or swallow mercury?

Due to its strength, metal is used to construct robots, space technology, electronics, and airplanes. Professional sports equipment is produced with the addition of this element. The extraction of the strongest substance occurs mainly on the island of Madagascar and in the Kingdom of Norway. And the production of the isotope itself is in China and the Russian Federation. One unit of scandium is equal to 4 dollars.

7. Rhenium

The valuable silver-colored metal is in demand in the construction of rocket launchers. The high price is due to material costs during the manufacturing process. So, to get 100 grams of metal, you have to use copper and molybdenum ore weighing 200 tons.

Rhenium is very refractory, the melting point is 3459 degrees. Large deposits of rhenium are concentrated in the Republic of Chile. There is also a monopoly company producing reserves of valuable metal. Price opened in Germany 1 g. rhenium is approximately $5.

Rhenium is recognized as the rarest element, but without it it is unthinkable to manufacture high-strength fire-resistant objects, for example, space engines and turbines.

6. Palladium

The metal is anti-corrosion and ductile. Discovered in 1803, the element was named after the ancient Greek goddess Pallas Athena. In the modern world, jewelers have become interested in palladium. Due to the fact that the metal is inexpensive, fusible, and capable of maintaining an excellent appearance for a long time, palladium jewelry is gaining justifiable popularity.

Due to its anti-corrosion properties, palladium is involved in cleaning systems. The largest supplier of natural metal is Russia, followed by South Africa. In the financial sector, stock brokers are interested in palladium. You can sell or buy precious metal for $20.

5. Rhodium

The metal, which costs $45 per unit, is rare in nature. Annual production amounts to a couple of tens of tons. Colombia, the Russian Federation and South Africa are famous for their rich deposits. Much of the extraction is used as a catalyst to create compounds used in the automotive industry.

 Few people know that due to its reflective properties, machine mirrors are made from rhodium.

But the main merit of high-hardness metal is its use in the construction of nuclear reactors. Rhodium has also found application in jewelry. The metal is used in alloys to increase the strength of precious items, as well as to impart a special shine.

4. Gold

It is popularly believed that this precious metal is the most valuable and expensive. Chemical element No. 79 Au is mined in nature as nuggets. Without processing, gold has a yellow tint. The melting point of aurum is a little more than a thousand degrees. It is now impossible to name the discoverer of the precious metal, since gold mining leads back to the Bronze Age.

The leaders in production are the Russian Federation, China and the USA. Jewelry, dental, electronic, food spheres - everywhere there is the possibility of using a noble chemical element. When melted, gold acquires the properties of “infinite” elongation. Thus, 1 gram of precious metal can be stretched over 283 kilometers.

The unique quality is used in textiles, for the production of gold threads. The largest nugget was discovered in 1872 at the Hill End mine in Australia. As many as 83.2 kilograms of gold were sealed in a mass with quartz. The price of 1 gram of the noblest metal is 40 - 50 dollars.

3. Platinum

The third place is occupied by the popular silver-colored metal. In nature, it exists exclusively in the form of alloys. The advantages of platinum are ductility, impeccable appearance and density. It is difficult to obtain platinum, because the metal is rare earth. Production requires a number of serious chemical processes.

Therefore, the cost of one unit starts at $50. But platinum is used everywhere: in jewelry, in the manufacture of medical instruments, in the production of electronics, in aeronautics, even in weapons. Large deposits of platinum in America, the Russian Federation, the African Republic and Canada.

2. Osmium 187

The production of valuable metal is a complex process that takes at least 36 weeks. The resulting fine-crystalline powder, Osmium isotope - 187, ranks first among metal compounds in density. The main areas of application of the isotope are science and medicine. With the help of osmium, cornerstone research discoveries were made.

In medicine, metal is used to make high-tech measuring instruments. But an important area of ​​application of the isotope is aerospace. The only place famous for the production of unique metal is Kazakhstan. The cost of one unit of osmium starts at $10,000 per 1 gram. The Guinness Book records the price at $200,000.

An artificial derivative that has unprecedented qualities, which leads to an astronomical cost. Thus, 1 gram of californium produces as much energy as an average nuclear installation produces. The isotope is produced in the Russian Federation - in the city of Dimitrovgrad, and in the USA - in Oak Ridge.

The isotope invented in California has valuable properties due to the release of neutrons. California - 252 discovers deposits of valuable minerals. Neutrons also shine through places inaccessible to humans and can find microscopic damage in high-tech equipment. It is important that californium-252 is widely used in antitumor medical therapy.

The truly exorbitant price for 1 gram of metal ranges from $6 to $10 million, which is explained by astronomical costs and the unique technology for producing the valuable substance. It is possible to produce 40 micrograms of the element per year.

 Only 9 grams of radioactive metal have been created in world history.

In the above list, metals change places every year, cheap ones become more expensive and vice versa. Exceptions include californium and osmium, due to the strong price gap.

Variety of metals

The earth is rich in metals, as evidenced by the periodic table of Mendeleev. And each group finds application in a variety of industries. The cost of one gram of an element depends on its useful qualities, the total amount in the world, as well as labor and material costs during extraction. That is, the richer the metal is in useful properties, the more difficult the extraction process and the greater its value.

A separate line includes precious metals, which not only serve as raw materials for the manufacture of jewelry, but are also considered a good investment. Buying precious metals is a sound business move because, compared to foreign currency, they retain purchasing power for decades.

There is a common myth that platinum is an order of magnitude more expensive than other metals. Surprisingly, this opinion is far from reality. All chemical elements on earth, including metals, are divided into two groups. These are elements of natural origin and compounds obtained artificially. The price of metals created in laboratories exceeds the cost of natural ones, especially if the process is accompanied by material costs.

What is the most expensive metal in the world and what is it used for?

To the surprise of many people, we can assure you that the most expensive metal in the world is not platinum or even titanium! There are substances that are much more expensive than these jewelry delights. We'll talk about why they are so valuable and where they are used. Below are the most expensive metals in the world. The top is based solely on scientific research into the actual price of the material.

the most expensive metals in the world. Prices and characteristics

There is a huge variety of substances on the planet, but most of them are very cheap. Common materials are not of high value; they are often used to improve the comfort of ordinary citizens. At the same time, experts identify several truly unusual materials, the cost of which is amazing. The most expensive metals in the world:

1. Our top 5 most expensive metals in the world opens with Californian 252. It cannot be obtained naturally, so to extract even one gram will require the long work of an entire team of chemists. This is not an independent element, but one of its isotopes, which has unusual functions. The cost reaches 10 million dollars per gram. In one year, a large laboratory can produce only 30 g of precious material. And this is with regular work and a full staff. That is why its price is so high. The element is mined exclusively in Russia and America.
2. Osmium 187 is another expensive isotope, the production of which will take a team of professionals up to 9 months. The black crystalline powder with slight purple hues is quite fragile. It is used in the chemical industry as a catalyst during laboratory experiments. Sometimes it is used to create medical devices of increased precision. Osmium is produced exclusively in Kazakhstan, the price is $200,000 per 1 g.
3. Tritium is a unique substance from which special lighting is made. It is widely used for research purposes. Purchasing 1 gram will require a capital of at least $30,000.
4. Plutonium is very dangerous and fragile, so work with it is carried out exclusively in special clothing. The material is radioactive and can cause irreparable harm to humans. In appearance, it is not much different from the usual silvery metals, except that upon closer examination one can notice a whitish tint. It is used to make nuclear weapons and fuel for space rockets. Price 1 g – $4,000.
5. Platinum is highly valued in the market. It is especially in demand among jewelers who create luxury jewelry and accessories. One gram of the substance can be purchased for about $60. It is quite dense and flexible, which makes it easy to make beautiful things from it. Platinum is also used in medicine, electronics and astronautics.

For those who want to know more about the most expensive metals in the world, the top 10 in the following video will show rare specimens. All of them are obtained through exceptional labor and, in most cases, require the intervention of professionals. Artificially created substances are very expensive, because their production costs a research center several million.

People often don't know the answer to the question of what is the most expensive metal in the world. Some call it gold, others call it platinum, but both options are very far from the truth.

As we can see from the above rating, the most expensive precious metal in the world is several thousand times more expensive than Pt. Due to extremely limited production, almost no one knows about the most valuable materials.

However, in the age of the Internet, it has become possible to obtain almost any information. A person can get acquainted with the latest developments of modern scientists and learn about the features of unusual substances.

The most expensive metal in the world, Californian, looks like a sparkling star. The bright white color and silvery shimmer create a captivating effect. Unfortunately, not everyone will be able to see this miracle with their own eyes. It is produced in special laboratories, where unauthorized entry is strictly prohibited.

The unusual substance was discovered in the 1950s by Glenn Seaborg. Initially, it was invisible to the human eye, because it consisted of only a few atoms.

It was obtained in reactors where dangerous radioactive elements were split under the influence of neutrons. Due to a well-tuned nuclear reaction, scientists were able to obtain a sparkling product.

It is logical to assume that the material extracted from hazardous elements is also radioactive. This is one of the reasons why it is not used in jewelry.

Californium is actively used in nuclear separation experiments. Thanks to him, space exploration is carried out. The isotope serves to simplify and speed up the search for gold or silver, oil or water. Determining the integrity of space and aircraft has become much easier with the advent of this expensive element.

Despite its toxicity, it is used for medical purposes. This is a source of healing light that destroys infected tissues, leaving healthy ones intact. After the introduction of this substance into the human body, active destruction of atypical cells begins. After the invention of californium, neutron radiosurgery was recognized as an effective method of treating many diseases.

If scientists achieve a reduction in the cost of extracting valuable material, this will entail a huge number of related inventions. Humanity will be able to make wider use of nanotechnology, improve the capabilities of medicine and become more active in exploring space.

1. California 252

The price for this metal is about 10 million dollars per 1 gram. But even the richest people on the planet can’t buy it. And all because there is no more than 5 grams of it. The substance is radioactive. During the decay period, one gram of it releases as much energy as 200 kilograms of radium.

Californium was produced artificially in 1950 by Seaborg's group at the University of California, Berkeley. But the name comes from the institute itself.

As the authors themselves wrote, they wanted to indicate with this name that discovering a new element was not as difficult as it was for American pioneers to reach California a century ago.

2. Osmium 187

The metal appears in the form of a fine crystalline powder. Its price per gram is 200,000 thousand dollars. Like its cousin, osmium exists in isotope form. It is not found in nature in its pure form, so the extraction process is very complex. Its duration is nine months.

3. Rhodium

As for the price for one gram of rhodium, it is 113.1 dollars. Unlike the first two metals, rhodium occurs in its pure form in nature. If we talk about its quantity, then the world estimates several tons. Every year, archaeologists and scientists mine quantities of metal that amount to only hundreds of kilograms. The metal is similar in appearance to aluminum, but is much harder.

4. Platinum

Platinum is more common than californium. Its price per gram is 52.7 dollars. Platinum is sometimes called white gold. It is not found in nature in its pure form. Most often it is found in alloys with other metals. The separation takes place in special boilers with a mixture of hydrochloric acid and nitric acid. Other chemical reactions are also used.

5. Gold

If you decide to buy 1 gram of gold, you will have to pay 56.9 dollars for it. Gold is considered the most popular metal in the world. In nature, it is found exclusively in its pure form. Gold does not corrode. It is compact, uniform and great for creating jewelry. Interesting fact: from 1 gram you can get a wire whose length is 2.4 km.

6. Osmium

Osmium sells for $41.6 per gram. The smell, however, is unpleasant. This is where the metal got its name, which translated from Greek means smell. It cannot be found in its pure form in nature. So you will have to look for minerals along with iridium. Osmium is quite scarce in the earth's crust, which is why the price is so high. About 100 kilograms of this substance are mined in America every year.

7. Iridium

Iridium will cost you only $35 per gram. Iridium has a silvery-white color. This is what reminds me of tin. The metal is quite fragile, given its high hardness and weight.

Iridium is used as an additive to platinum. The resulting alloy will be three times harder than platinum, even at a ratio of 1 to 10.

It should also be said that an alloy of platinum and iridium is used in the manufacture of length and weight standards.

8. Ruthenium

For one gram of ruthenium you need to pay 28 dollars. The metal, although hard, is quite fragile. It is included in the platinum group. Ruthenium is typically used in the manufacture of printed circuits and resistors in the electronics industry.

It can be used to produce chlorine. Ruthenium was discovered by Kazan University professor Karl Klaus. This was in 1844. Ruthenium was named after Russia. The name was proposed in 1828 by G.V.

Ozanne for an element which he mistook for a new one.

9. Palladium

The price of palladium per gram is 21.2 dollars. It has a very beautiful white color. The substance is light and flexible. It is easy to melt. Corrosion resistant.

Palladium has high flexibility and ductility when compared with other platinum group metals. Palladium was discovered by an English chemist named William Wollaston in 1803.

The scientist isolated it from platinum ore, which was brought from South America.

To isolate the metal, the chemist dissolved the ore in aqua regia, and then neutralized the acid with a NaOH solution. Next, I precipitated platinum from solution using ammonium chloride. If we talk about the name of the metal, it comes from the name of the asteroid Pallas, which was discovered by the German astronomer Olbers in 1802. In other words, shortly before the discovery of palladium.

The most expensive metals in the world

The time has passed when the most valuable metal on our planet was gold. Now money has taken over its role in trade relations, and the newly discovered chemical elements have significantly pushed gold back from the list of “The Most Expensive Metals.”

California-252

The most expensive metals in the world are California-252. It was obtained in 1960, at the University of California, where it got its name. A gram of this substance costs more than 10 million. This is due to the absence of the substance in its natural form, and there is no more than 10 grams of California-252 on the planet.

The price of a substance is also determined by its properties. California-252 has an important role in medicine. A gram of reactor produces a number of neutrons equal to the number of neutrons produced by a nuclear reactor. In medicine, this substance is used to treat cancer cells. It only takes a few micrograms.

Applications California-252 is also used for ore mining and in space exploration.

The most expensive precious metal in the world is rhodium.

Many, wondering which metal is the most expensive, may mistakenly answer that the most expensive is gold, but this is not so. Due to its rarity and difficulty of extraction, rhodium tops the list of precious metals with the highest price.

The price is also affected by the fact that in most applications, there are no alternatives to rhodium. This primarily concerns the use of rhodium in catalysts (in the form of an alloy with platinum) for the production of nitric acid.

Rhodium is also used in the production of:

• glass and liquid crystal screens;
• rhodium detectors necessary for measuring neutron fluxes in nuclear reactors;
• spectrometers;
• mirrors for high-power laser systems;
• cultivated gemstones;
• contacts;
• jewelry - as coatings that provide corrosion resistance, scratch protection and high shine.

The most expensive metal in the world is California-252

The list of the 10 most expensive metals in the world is headed by the rarest isotope - californium-252. Its extreme high cost is due to the extremely complex production process and its unique properties. With just one gram of this substance it is possible to generate energy comparable to the power of a small nuclear reactor. The areas of use of californium-252 are also highly specialized:

• Medicine. It is used as a source of neutrons, allowing for radiation therapy of cancer tumors in cases where other methods are powerless.
• Damage detection. Thanks to the unique properties of californium, it is possible to “scan” elements of reactors and aircraft, identifying faults that cannot be found using x-rays.
• Geology. The use of California-252 helps to discover gold deposits, potential sites for silver and other minerals in the bowels of the earth.

The most expensive metals in the world: rating with cost indication

Investing in metals has always been profitable, especially if it is gold and silver. It is believed that gold is the most highly valued. This is not entirely true.

Prices for natural resources are determined by the market. Supply and demand play a role, as do other factors. We present the ranking of the most expensive metals in the world.

What affects the price of metal?

The price of metal is determined based on the results of trading. Transactions are carried out on the stock exchange, which serves as a kind of marketplace for buyers and sellers. Anyone involved in metal products can monitor price changes in real time.

There are several exchange platforms in the world:

• in London;
• in Tokyo;
• in Shanghai and other cities.

The number of deposits of a particular substance on the planet is of great importance in determining the cost of metals. In addition to the common iron ore and aluminum, rare ones are also found. An increase in demand for such products increases their price. Let's find out how much the most expensive metals cost.

Top most expensive metals

Substances of this group are necessary for humanity. They are widely used in the production of key products:

• alloys (used everywhere, have strength);
• tools;
• conductors of electric current.

If at the beginning of the last century humanity knew about the existence of 65 different elements of the metal series, in the 21st century another 31 were added to them. Among the most expensive in the list presented below will be those discovered by scientists several years ago.

10th place – Ag (silver), $0.5 per gram

Silver has been known to people since time immemorial. The main reason is its presence in the upper layers of the earth in the form of nuggets. Among its properties: plasticity, malleability. It has a light color and a silvery sheen.

Silver in coins and bars

The largest deposits of silver are located in North America. To a person who is far from technological innovations, it may seem that metal is mainly used to make jewelry, spoons and coins. In fact, silver is widely used, using its properties of high electrical conductivity and as a catalyst in chemical oxidation reactions. Silver is also used to disperse clouds.

At the end of 2018, one troy ounce of silver (31.1 grams) costs $14.84 on the New York World Exchange.

9th place – Ru (ruthenium), $2 per gram

Ruthenium was discovered by Professor Klaus, who taught in Kazan at the end of the 19th century. He isolated the pure element from platinum ore brought from the Urals. The name of the element repeats the Latin “Ruthenia”, which means “Rus”. It is actually a platinum metal.

There are three ways to obtain a pure substance:

1. from technetium nuclide with mass number 99;
2. when purifying platinum from impurities;
3. when processing nuclear materials (significant amount).

On exchanges it is traded at $60-65 per troy ounce. Used as a catalyst, in alloys, for resistors and ion channel studies.

8th place – Sc (scandium), $3.4 per gram

The silvery metal scandium is light in weight and has a yellowish tint, by which it is easily recognized. It was first announced by a chemist from Sweden, Nilsson, so scandium received its name in honor of an entire region in northern Europe.

One isotope of the substance is known. It is used in alloys to increase electrical conductivity, in robotics, in the production of weapons, and to obtain materials of increased strength. The properties of the element are not fully understood, but scientists call it the metal of the future.

It is predicted that scandium will strengthen its position in the ranking of the most expensive chemical elements.

7th place – Re (rhenium), $4.7 per gram

This position is occupied by the expensive and rare metal rhenium with high density. Named after a large German river - the Rhine.

Rhenium in ingot and cubic form

Mendeleev called it trimarganese, but it was discovered in the first quarter of the 20th century by chemists from Germany. Obtained by isolation from raw materials:

In deposits of different countries you can find no more than 13,000 tons. Demand for rhenium is recorded annually, as it is necessary for the creation of aircraft and missile components. The substance has a high melting point of 3186°C. Contacts made from this expensive element clean themselves and last longer than others.

6th place – Pd (palladium), $19 per gram

Platinum will be discussed below, but another metal was extracted from its ore - palladium. It is lightweight, similar in appearance to its counterpart, but very flexible.

Palladium is widely used in jewelry making

It is noteworthy that palladium is rarely found in the crust of the globe; it is used in the manufacture of coins and jewelry, in electroplating, and in medicine. This substance is mined in Russia (Norilsk), eastern Canada, and South Africa.

5th place – Rh (rhodium), $27 per gram

Silvery shiny metal with a pinkish tint is in great demand in the world. Like palladium, it was discovered when working with platinum.

Alloys with rhodium have a characteristic pinkish color

Not only is it rare and expensive, but it is also scattered. This means that it exists only in the form of an isotope. It is impossible to find a rhodium nugget. The price is affected by demand and the lack of large deposits. The connection between rhodium and gold and another metal, iridium, is known: osmic iridium has the highest content of this expensive substance.

4th place – Pt (platinum), $30 per gram

The oldest platinum products were found in South America in the foothills of the Andes. From there it was brought to Spain. In Russia, the expensive element was found in the Urals during gold mining. Even in ancient times, people learned to distinguish platinum from silver, revealing extraordinary refractoriness.

Platinum is an inert element. It can only be dissolved in a concentrated mixture of nitric and hydrochloric acid (aqua regia) and bromine. The substance is widely used in industry. It is used to make electrodes, parts for microwave ovens, and laboratory glassware. Used in the production of jewelry.

3rd place – Ir (Iridium), $35 per gram

A dense, expensive and very rare metal found in meteorites. The discovery of iridium belongs to the Englishman Tennant. About 3 tons of the substance are mined annually around the world.

Iridium has two stable isotopes. The element is used for various purposes:

• in the manufacture of automotive engine parts;
• for nuclear reactors, including in Russia;
• in paleontology;
• for rocket fuel tanks.

Does not corrode even at high temperatures. The price in the markets fluctuates and can reach $45 per gram, which is higher than gold.

2nd place – Au (Gold), $40 per gram

Gold is more attractive than other rare metals because it has a characteristic yellow color. It is one of the most expensive and in demand in the world: it is used in the chemical and electronic industries, for making jewelry, and in dentistry. The best children's and ladies' jewelry is made from 750 gold.

55 thousand tons of expensive metal are today in safe deposit boxes and bank vaults as savings and government reserves. Just as oil deposits are valued today, so have mines been valued at all times.

1st place – Cf (californium)

It's time to find out which metal is the most expensive in the world. His name comes from the state of California. At the University of Berkeley it was created artificially. California is the most expensive metal on earth. This is due to the following reasons:

• rare, not found in the earth's crust (produced in the USA and Russia);
• It takes 8-18 months for production.

The production time for 1 gram of Californian can reach 1.5-2 years

To isolate, the transuranium element curium and the radioactive plutonium must be placed in a nuclear reactor and irradiated. Everything that remains after a few months is subjected to chemical attack. Californium is also called the most expensive precious metal in the world, although it is not used to make jewelry. The fact is that it is used to treat tumors. The element is also used as a source of neutrons.

There are 8-9 grams of metal stored in the world. The price of the most expensive metal in the world is $250 million per gram.

The most expensive metal in the world, price

Stop a passerby on the street and ask which metal is the most expensive in the world. “Of course it’s gold!” - he will answer immediately. If a passerby likes to solve crossword puzzles, then instead of gold he will remember platinum or palladium. And fans of scientific and educational programs will immediately assume uranium. They are all wrong.

Gold is neither the most expensive nor the rarest metal on earth. It's simply the most convenient. A chemically inert metal that does not corrode, is rare enough to be valuable, and of course, a beautiful, pleasing finishing material. Gold does not lose value for centuries - even if it is in a pirate chest at the bottom of the ocean.

There are many much more valuable and rare metals in the world that are used in various areas of our lives. But it can be difficult to determine the exact price of many of them. The rarest metals are mined by humanity in such minute quantities that most often they cannot be purchased - every microgram of such a substance is strictly registered with the state and is used for scientific research or industrial purposes.

Those metals that can still be purchased are mined by one or two countries in small quantities, so their price is subject to constant market speculation and manipulation. Large market players inflate and destroy the value of rare substances and stock prices in their own interests, so their price is a rather arbitrary number.

List of the most valuable metals:

• californium;
• osmium;
• platinum;
• gold;
• rhodium;
• palladium;
• iridium;
• rhenium;
• scandium.
• silver.

Californium

The radioactive actinide californium, or rather its most used isotope 252, has virtually no price, since it cannot be purchased. It is produced by long-term irradiation of plutonium in a nuclear reactor, and only two laboratories on Earth carry out such a complex procedure.

Moreover, this isotope has a half-life of only three years, meaning it is produced longer than it is stored. One gram of this substance is estimated within a wide range - from 10 to 250 million dollars.

Osmium

Regular osmium itself is not that expensive - $15 per gram. But its rare isotope 187 is incredibly difficult to obtain.

Bearing the title of the densest and heaviest substance in the world, this metal is mined only in Kazakhstan and is used in science. One gram of such an isotope is estimated at from 10 to 200 thousand dollars.

Platinum

A silvery analogue of gold, platinum is mined from natural alloys with other metals in many countries around the world, including Russia.

Used as a catalyst , in industry and electronics, and as a jewelry material. The price of platinum on the market ranges from 20 to 50 dollars per gram.

Gold

A familiar metal of a yellowish or pink hue, gold is found in nature in the form of pure nuggets.

Rare, but easy to mine and process, gold is deservedly the most popular valuable metal on earth - used in many industries, jewelry and economics. The cost of one gram remains at $40.

Rhodium

Rhodium, a rare relative of platinum, has not only similar characteristics, but also unique reflective abilities.

Mined in tens of tons per year in Africa, Canada and Russia , it is used as a catalyst, as well as in the manufacture of mirrors, headlights and jewelry. The price is about the same as that of gold - 30-40 dollars per gram.

Palladium

Another relative of platinum differs from it in a positive direction in that it is slightly more common, as well as low weight and ease of processing.

The main producer of palladium is Russia , and it is used in jewelry and industry. The cost reaches $30 per gram.

Iridium

The incredibly hard and corrosion-resistant metal is not used on its own, but is a valuable companion to other metals in alloys, giving them hardness and wear resistance.

Balls of high-quality fountain pens, tools, scientific instruments - metal alloys with iridium are used everywhere. The cost of one gram is 15-17 dollars.

Rhenium

One of the most refractory, rare metals, rhenium is used in the construction of turbines and jet engines, as well as in electronics.

The cost of a gram reaches up to $5.

Scandium

Named after Scandinavia, mined in Norway, scandium, due to its lightness and strength, is used everywhere in modern technologies - robotics, space and sports industries.

Up to 4 dollars per gram.

Silver

The list is completed by the familiar and familiar silver. Mined all over the world, this metal is valuable for its electrical conductivity, ease of processing, durability and appearance.

It is used in jewelry, industry, photography, and is traded at one dollar per gram.
