Description
Soft, ductile, silvery-gray, rare earth metal.
Uses
It is used in modest amounts in special lasers and solid-state devices.
Sources
Found with other rare earths in monazite sand, which typically contain 0.03% terbium. Other sources are xenotime and euxenite, both of which are oxide mixtures that can contain up to 1% terbium.
Pronounciation (English)
TUR-bi-em
