On Earth, there is a mass of different chemical elements ( metals ), but not all of them are found in the natural environment very often .
This is the main factor that determines the price of the most expensive metals in the world.
I’m sure many people do still believe that the most expensive metal – it’s gold . However , gold is only the most popular precious metal , but not the most expensive , which is found on the planet. Moreover , the most expensive metal on earth – it is not platinum, although it is certainly more expensive than gold .
However, the metals are in the world , the price of which reaches astronomical figures. These metals are the isotopes of californium and osmium , like Nos. 252 and 187.
Thus, the most expensive metal in the world – a stone with a beautiful, but slightly technically called – of California 252. The price of one gram of the metal is 10 million dollars. And all because of the isotope in the world there is no more than five grams.
The most expensive metals frequently radioactive, and California as well . In its decay releases energy equivalent to 200 kg of decay of radium. Although the most expensive precious metal, and takes the first place in the ranking of him probably will not get to make beautiful jewelry, such as gold or platinum.
In second place relative of California – Osmium , rather, Osmium -187 . Its on the planet to order more , so gram of metal is worth 200,000 dollars. It should be noted that the osmium is not found in a pure form. It is produced artificially . Production of Osmium – a time-consuming process that takes up to 9 months.
In the top three and gives succinct answer to the question , what is the most expensive metal in the world – Rhodium . It is found on the planet in its purest form , the amount estimated in tonnes. Each year extract only a few hundred kilograms of rhodium. Metal looks like all the usual aluminum, but it is much harder .
4 positions located platinum. Per gram of the metal will have to pay 52.7 dollars. Often referred to as white gold, platinum . As usual, the metal is not found in the natural environment , it is extracted from alloys with other elements. The synthesis of platinum is supplemented with nitric acid and hydrochloric acid.
It was only on the fifth line is warmly loved and respected gold. Price of 1 gram of gold is about 57 dollars. This metal is the most popular in the world. It should be noted that the gold is found in nature only in pure form. It is able to resist corrosion. Gold is very compact , homogeneous , and therefore is an ideal material for making jewelry . For clarity : of 1 gram of gold can be pulled thread long by 2.5 km .
Natural osmium is in sixth position . Gram of the metal will cost 41.6 dollars. It should be noted that this metal is not very pleasant flavor , so it was called osmium ( from the Greek ” smell “). Metal also can not get in nature. As usual it is produced together with iridium . The earth’s crust of the metal is extremely small, so it is costly. For example, in the United States per year produces about a hundred pounds of osmium .
Seventh position and iridium. It is worth 35 grams of metal dollars. Externally iridium is somewhat similar to tin. Despite its high hardness , iridium is very fragile . It is used as an additive to platinum.
Ruthenium and palladium respectively occupy 8 and line 9 . The price of metals is similar – 28 and 21.2 dollars per 1 gram.
