Description
Cerium is a lustrous silvery-dark grey metal that oxidizes readily in air. Finely divided cerium metal is very unstable in air. The metal is malleable and will likely ignite if cut with a knife.USES
Cerium metal is added to aluminum, magnesium, cast iron, steel, and superalloys to increase their strength.
Cerium is widely used in automotive catalytic converters to reduce pollution.
