Ruthenium (Ru)
Ruthenium (Ru)
Discovered in 1844, ruthenium is a member of the platinum group and occurs naturally where other group members are found.
Ruthenium is a hard, white metal with four crystal modifications. Non-tarnishing at room temperatures, it is explosive when oxidized. Ruthenium is an effective hardener for platinum and palladium and is frequently alloyed with them.
It is a versatile catalyst, and an alloy of ruthenium and molybdenum is reported to be superconductive at 10.6 °K.
Compounds in at least eight oxidation states have been found, and ruthenium compounds resemble those of cadmium.
