History

Jöns Jakob Berzelius and Wilhelm Hisinger discovered the element in ceria in 1803 in Sweden. Klaproth discovered it simultaneously and independently in some tantalum samples in Germany. Carl Gustaf Mosander, who worked closely with Berzelius, prepared metallic cerium in 1825. Cerium was named for the asteroid Ceres

DiscoverersW. von Hisinger, J. Berzelius, M. Klaproth
Discovery LocationSweden/Germany
Discovery Year1803
Etymology (Name Origin)Named after the asteroid, Ceres, discovered two years before the element.
PronunciationSER-i-em (English)
Cerium is considered to be moderately toxic
Seawater contains 1.5 parts per trillion of cerium

Uses

Cerium is used in carbon-arc lighting, especially in the motion picture industry. Cerium oxide is an important component of glass polishing powders and phosphors used in screens and fluorescent lamps. Cerium compounds are also used in the manufacture of glass, both as a component and as a decolorizer. Its oxides are used in the optics and glass-making industries. Its salts are used in the photography and textile industry. Used in high-intensity carbon lamps and as alloying agents in special metals.

Sources

Most abundant rare earth metal. Found in many minerals like monazite sand [Ce(PO4)].
