Cerium (SER-ee-em) was discovered by Jöns Jacob Berzelius and Wilhelm von Hisinger, Swedish chemists, and also independently by the German chemist Martin Heinrich Klaproth, in 1803. It is one of the rare earth elements. Cerium is considered to be moderately toxic.[1]
Cerium is a reactive, soft, gray, lustrous metal that is malleable and ductile.[2] It is also somewhat flammable.[3]
Uses
Cerium is used for a number of things, including carbon arc lights (used in the movie industry, and other places),[4] the walls of self-cleaning ovens, and even lighter flints.[5] Cerium oxide and other Cerium compounds are also used for glass treatment.
