Ruthenium

Uncategorized

Ruthenium is a chemical element with the symbol 44. It is a rare transition metal belonging to the platinum group. Like the other metals of the platinum group, ruthenium is inert to most other chemicals. Russian-born scientist of Baltic-German ancestry Karl Ernst Claus discovered the element in 1844 at Kazan State University and named ruthenium in honor of Russia Ruthenium is usually found as a minor component of platinum ores; the annual production has risen from about 19 tonnes Most ruthenium produced is used in wear-resistant electrical contacts and thick-film resistors. A minor application for ruthenium is in platinum alloys. A new application of ruthenium is as the capping layer for extreme ultraviolet photomasks. Ruthenium is generally found in ores with the other platinum group metals in the Ural Mountains and South America. Small but commercially important quantities are also found in pentlandite extracted from Sudbury, Ontario deposits in South Africa
