How much is the most expensive metal

Many years passed since the time when DI Mendeleev presented his first table of chemical elements to the public in 1869. And today many residents of our planet are concerned with a very interesting question: "What is the name and cost of the most expensive metal on earth?" And if a more or less correct idea has already been formed about precious stones, then things are much worse with knowledge of metals. Only a few can name the most expensive metal.

So, this is the Osmium isotope of the 1870s. In the periodic system of Mendeleev, the most precious precious metal is numbered 76. The whole point is that the isotope Osmium is the hardest of all substances that are discovered by mankind. Incredibly, the density of this metal is 22.62 g / cc. Osmium differs characteristic sharp smell and silvery color. Due to its physical and chemical characteristics, the metal is used in the nuclear industry, in the production of jewelry and in pharmaceuticals.

No less interesting that the most expensive metal personally we can hardly see. The thing is that today on the black market of metals for 1 gram of Osmia will have to pay more than 200 thousand dollars. The first official exporter of Osmia was Kazakhstan, which in 2004 offered one gram at a price of $ 10,000. In addition to Kazakhstan, no country in the world offered the Osmium isotope, because the process of its production is a very complicated task. The metal is produced by calcination of platinum concentrates at temperatures of 900-1000 ° C.

Purely theoretically the most expensive metal is California 252. As of 2010, the price of 1 gram of California was 6,500,000 dollars. However, the world's reserves of this metal are only a few grams, and only two countries (Russia and the US) produce about 20-40 micrograms per year. The physical properties of California are more than impressive: only 1 μg is capable of emitting 2 million neutrons per second. Due to these characteristics, the metal is used to treat malignant tumors in medicine, as a point source of a large number of neutrons.

Another noble metal is platinum. And if he does not pretend to be the "Most Expensive Metal", he is among the 5 most common precious. If you turn to history, platinum was extracted already in the 12th and 14th centuries by tribes that lived in the Andes region. He got to the inhabitants of Europe in the 16-17 centuries. 5 countries are engaged in the development of platinum locations: the USA, Russia, China, South Africa and Zimbabwe.

Most often, coins are produced from platinum, but, in contrast to gold and silver, they have been coined from platinum relatively recently.

Metal is successfully used in the manufacture of medical, dental and laser technology. They cover the submarine hulls to protect against corrosion.

In the jewelry industry, platinum is also of high value.

As of January 1, 2013, the average price for 1 gram of platinum is about $ 70. The main market was always Japan, but today the palm of the championship was confidently adopted by China.

By the way, every year the world jewelry industry consumes more than 50 tons of platinum, and China accounts for about 50% of all sales.
