Osmium (CAS NO.7440-04-2) is found in nature as an alloy, mostly in platinum ores. It was discovered in 1803 by Smithson Tennant and William Hyde Wollaston in London, England, and was published in 1748. In 1803, Smithson Tennant analyzed the insoluble residue and concluded that it must contain a new metal, and, in 1908 cheaper catalysts based on iron and iron oxides were introduced for the first pilot plants. Nowadays, it is primarily obtained from the processing of platinum and nickel ores.
Osmium (CAS NO.7440-04-2) is a hard, brittle, blue-gray or blue-black transition metal in the platinum family, and is also used in alloys, with platinum, iridium and other platinum group metals.
