Description and Uses
Since ruthenium is rare and difficult to isolate in pure form, there are few uses for it. Itsmain uses are as an alloy to produce noncorrosive steel and as an additive to jewelry metalssuch as platinum, palladium, and gold, making them more durable.
It is also used as an alloy to make electrical contacts harder and wear longer, for medicalinstruments, and more recently, as an experimental metal for direct conversion of solar cellmaterial to electrical energy.
Ruthenium is used as a catalyst to affect the speed of chemical reactions, but is not alteredby the chemical process. It is also used as a drug to treat eye diseases.
