Ruthenium

MATERIAL OVERVIEW

Characteristics: A rare silvery polyvalent hard white metal, ruthenium is a member of the platinum group. Ruthenium is inert to most other chemicals and insoluble in acids and in aqua regia. Attacked by alkaline oxidants (conc. NaOH solution), and by fused alkalies. Most ruthenium produced is used in electronics for wear-resistant electrical contacts and the production of thick-film resistors.
