Ruthenium Properties




Ruthenium is a rare transition metal belonging to the platinum group of the periodic table. The Russian scientist Karl Ernst Claus discovered the element in 1844 and named it after Ruthenia, the Latin word for Rus'. It is used for wear-resistant electrical contacts and the production of thick-film resistors. A minor application of ruthenium is its use in some platinum alloys. It is a versatile catalyst. It was also suggested as a possible material for microelectronics because its use is compatible with semiconductor processing techniques.
