Description and Uses
Ruthenium is used in wear-resistant electrical contacts and the production of thick-film resistors. Its use in some platinum alloys, and as a catalyst. It is a most effective hardeners for platinum and palladium. It is also used in some advanced high-temperature single-crystal super alloys, with applications including the turbine blades in jet engines and fountain pen nibs.
