萤石块/粉 (CaF2 75-90%) 蒙古
Fluorspar (CaF2) is the mineral form of calcium fluoride, also called fluorite. Pure fluorite is transparent, both in visible and ultraviolet light, but impurities usually make it a colorful mineral and the stone has ornamental and lapidary uses. Industrially, fluorite is used as a flux for smelting, and in the production of certain glasses and enamels.
