A minor application for ruthenium is in platinum alloys and as a chemical catalyst. A new application of ruthenium is as the capping layer for extreme ultraviolet photomasks in semiconductor lithography. Ruthenium is generally found in ores with the other platinum group metals in the Ural Mountains and in North and South America.

Ruthenium, chemical element, one of the platinum metals of Group 810 (VIIIb), Periods 5 and 6, of the periodic table, used as an alloying agent to harden platinum and palladium.

Ruthenium is one of the most effective hardeners for platinum and palladium, and is alloyed with these metals to make electrical contacts for severe wear resistance. It is used in some jewellery as an alloy with platinum. Ruthenium has no known biological role. Ruthenium (IV) oxide is highly toxic. Ruthenium is one of the rarest metals on Earth.

Periodic Table Ruthenium Ruthenium is a chemical element with symbol Ru and atomic number 44. Classified as a transition metal, Ruthenium is a solid at 25°C (room temperature).

Ruthenium was discovered in 1884 and is member of the platinum family. It is a rare metal and widely in electrical industry and in making alloys.
