More info

Terbium (Tb) Metal is a silvery, malleable, soft, and ductile rare earth element that can be cut by a knife. It is relatively stable in the air. It is never found in nature as a free element, however, it is readily found in minerals such as cerite, gadolinite, and euxenite. Terbium compounds are highly fluorescent and are frequently used to produce green phosphors.  HM stocks a wide variety of rare earth materials for use in electronics, petrochemicals, metallurgy, machinery, energy, environmental protection, agriculture, and other fields. We also offer pure metals and compounds for R&D applications.
