Many people mistakenly believe that is the most expensive metals in the world - it is platinum, gold and silver. But in fact there are other dense chemical elements that are hundreds of times higher than their cost. A high price is determined by such indicators as rarity, inaccessibility and properties.

Ruthenium Cost of 1 gram - 1,5 US dollars
Ruthenium opens the ten most expensive metals. The chemical element of bright silvery color differs by refractoriness, hardness and brittleness. Ruthenium is one of the rarest elements of the platinum group. For the first time it was opened by Professor Karl Klaus, who conducted research at Kazan University in 1844.The name of the element comes from the Latin Ruthenia, which means Rus / Russia. Ruthenium is widely used in jewelry production, electronic and chemical industries. It is used for making electrodes, wires, contacts, etc. The element also produces chlorine and alkali. The cost of 1 gram of metal is currently estimated at 1.5 US dollars.
9
Renium Cost of 1 gram - 10 US dollars
The ninth place among the most expensive metals in the world is rhenium .A chemical dense element of silvery-white color is also considered one of the rarest, hard-to-reach and sought after isotopes. Because of its high density, rhenium refers to the most refractory metals. Since the discovery of the element( 1925), it has been actively used in the chemical and electronic industries. It produces alloys for nozzles of jet engines, turbine blades, rocket technology, etc. This is the only refractory element that does not form carbides. On average, 1 gram of rhenium is estimated at $ 10.
8
Scandium Cost of 1 gram - 12 US dollars
Scandium is one of the most expensive metals in the world. The element of silvery color with yellow tint was first discovered in 1879, thanks to the Swedish scientist Lars Nilsson, who named it in honor of Scandinavia. The most valuable isotope is used in innovative technologies in the design of missiles, robots, laser technology, satellites and aircraft. Of alloys with this element, sports equipment is manufactured. The largest deposits of scandium are concentrated in Madagascar and Norway. One gram of metal is valued at $ 12.
7
Iridium Cost of 1 gram - USD 20
Iridium occupies the seventh line among the most expensive metals in the world. The isotope of silvery-white color looks like tin. It is very heavy, hard and fragile at the same time. Iridium is most often used to make alloys with other metals, for example, with platinum. Ornaments from this alloy are highly wear-resistant and very beautiful. Iridium is widely used in the manufacture of electrical contacts, precision chemical scales and surgical instruments. The world learned about the metal thanks to the British chemist S. Tennat, who opened it in 1803.At present, about one ton of iridium is consumed annually. Its supplier is South Africa - it is there that the deposit is concentrated. One gram of the isotope is estimated at about $ 20.
6
Palladium Cost of 1 gram - $ 30
Palladium is one of the most expensive metals in the world, which belongs to the platinum group. The silver-white isotope is distinguished by its fusibility and ductility. It is highly polishable, does not lose its gloss over time and is resistant to corrosion. It was discovered by the British chemist William Wollaston in 1803.The scientist decided to separate the unknown metal from platinum ore, which came from South Africa. Now palladium is actively used for making jewelry of different price category. Also, it is widely used in medicine and industry, thanks to its anti-corrosion properties. One gram of metal costs about 30 US dollars.
5
Gold Cost of 1 gram - 45 US dollars
Gold is located in the middle of dozens of the most expensive metals in the world. In nature, a noble isotope is found exclusively in pure form. Due to its plasticity and durability, gold is considered to be one of the most popular metals used for making jewelry. In addition, it is used in the electronics industry and dentistry. Some of the most expensive investment coins are minted from gold. The cost of 1 gram of a noble element is estimated at 45 US dollars.
4
Platinum Cost of 1 gram - 70 US dollars
Platinum takes the fourth place among the most expensive and precious metals in the world. It is a natural alloy of six isotopes, which has a silvery white hue. Platinum is one of the rarest elements. Its deposits are found mainly in Russia, the United States, China, South Africa and Zimbabwe. Platinum is used not only for the production of jewelry, but also for medical and industrial purposes. Previously, metal was considered to be of poor quality and was often used for counterfeit silver and gold articles. To date, 1 gram of platinum is estimated at an average of $ 70.
3
Rhodium Cost of 1 gram - 225 US dollars
Rhodium opens the three most expensive metals in the world. Since it has high reflective abilities, it is used in the manufacture of glass and mirrors. In addition, it is used for the production and processing of jewelry. Rhodium gives the products a shine and prevents them from getting dark, due to their high resistance to oxidation. One gram of the isotope is currently estimated at 225 US dollars.
2
Osmi-187 Cost of 1 gram - 200 000 US dollars
Osmiyy-187 is the second most expensive metal in the world. Its extraction is associated with some difficulties and takes about 9 months. One of the rarest isotopes in the form of black fine crystalline powder is the most dense substance on the planet. But despite this, the most valuable element is fragile enough. For scientific research, osmium-187 is of great importance, since it is used as a catalyst for chemical reactions, as well as for the production of measuring instruments with high accuracy. The cost of 1 gram of osmium-187 is 200 thousand US dollars.

California-252 Cost of 1 gram - 6.5 million US dollars
Tops the list of the most expensive metals in the world california-252 .The cost of 1 gram of california is estimated at 6.5 million dollars. Annually, about 30-40 micrograms of the element are produced, which justifies its inflated price. For all time, only 8 grams california-252 was produced. It was first obtained in one of the universities in California in 1951.Now it is created in the laboratory using nuclear reactors in Russia and the United States. The uniqueness of the isotope lies in its released energy, the power of which can be compared with the average atomic reactor. It is actively used in medicine and nuclear physics. With the help of california-252, malignant tumors are treated. Metal is able to detect damage in reactors and aircraft structures that could not detect X-rays. In addition, the most expensive element is used to discover new oil, gold and silver deposits.
