Where is Cerium Found?
Cerium is the most abundant so-called rare-earth metals. It is found in a number of minerals including allanite, monazite, bastnasite, cerite, and samarskite. Monazite and bastnasite are presently the more important sources of cerium.
Large deposits of monazite found on the beaches of Travancore, India and in river sands in Brazil, allanite is found in the western United States, and bastnasite can be found in Southern California will supply cerium.
What is Cerium Used For?
Cerium is a component of misch metal, which is extensively used in the manufacture of pyrophoric alloys for cigarette lighters. The oxide is an important constituent of incandescent gas mantles and is emerging as a hydrocarbon catalyst in self cleaning ovens. Cerium compounds are used in the manufacture of glass, both as a component and as a decolorizer.
