CERIUM
(Ce)
MATERIAL
OVERVIEW
Characteristics:
Gray, ductile, highly reactive metal. Attacked by
dilute and concentrated mineral acids and by alkalies.
Readily oxidizes in moist air at room temperature. It
has four allotropic forms. It is the second most
reactive rare-earth metal. Cerium forms alloys with
other lanthanides, it also forms a nonmetal with
hydrogen, as well as carbides and intermetallic
compounds. Decomposes in water; nontoxic.
Derivation:
Chemical processing and separation of ores.
Hazard:
May ignite on heating to 300 oF (148.9 oC). Strong reducing agent.
