Description
A rare earth metal of the yttrium group that occurs in the minerals gadolinite, euxenite, xenotime, and monazite. It is a silvery, ductile metal that exists in an alpha crystalline form at normal temperatures and a beta crystalline form and high temperatures (over 798 C). Metallic ytterbium is used in lasers, portable x-ray sources and phosphors that convert infrared radiation to visible light. Ytterbium oxide is used in special alloys, dielectric ceramics, and in special glasses.
