Ruthenium Information

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.

Used to harden platinum and palladium. Aircraft magnetos use platinum alloy with 10% ruthenium.
