Ruthenium (Ru)

Hard white metallic transition element. Found with platinum, used as a catalyst in some platinum alloys. Dissolves in fused alkalis, and is not attacked by acids. Reacts with halogens and oxygen at high temperatures. Isolated in 1844 by K.K. Klaus.

History

Jędrzej Śniadecki isolated the element in 1807, but his work was not ratified. Jöns Berzelius and Gottfried Osann nearly discovered ruthenium in 1827. In 1844, Karl Ernst Claus confirmed that there was a new element and isolated ruthenium from the platinum residues of the rouble production while he was working in Kazan University, Kazan. From the Latin word Ruthenia, Russia

Discoverers	Karl Klaus
Discovery Location	Russia
Discovery Year	1844
Etymology (Name Origin)	Latin: Ruthenia (Russia).
Pronunciation	roo-THE-ni-em (English)

Ruthenium is a suspected carcinogen and its compounds strongly stain the skin

Ruthenium is unaffected by air, water and acids

Uses

Ruthenium is used in platinum and palladium alloys to make wear-resistant electrical contacts. Ruthenium dioxide and lead and bismuth ruthenates are used in thick-film chip resistors. Fountain pen nibs are frequently tipped with alloys containing ruthenium. Ruthenium is a versatile catalyst. Used to harden platinum and palladium. Aircraft magnetos use platinum alloy with 10% ruthenium.

Sources

Found in pentlandite and pyroxinite.
