Application in Glass Products
Fluorite (Fluorite) is also known as fluorite, fluorite powder, fluorite powder. It is a mineral, isometric crystal system, and its main component is calcium fluoride (CaF2).
Contains more impurities, Ca is often replaced by Y and Ce and other rare earth elements, in addition to a small amount of Fe2O3, SiO2, and trace amounts of Cl, O3, He, etc. In nature, fluorite often appears in the form of fluorite, fluorite powder, fluorite powder, fluorite powder.
Fluorite in nature often shows bright colors, some can emit fluorescence. Mohs hardness 4, lower than steel, easy to scratch, brittle, sweet, astringent. Melting point:1270-1350℃. Density: 3.18g/cm³, refractive index: 1.434. It can be used for the preparation of hydrogen fluoride: CaF2 + H2SO4 = CaSO4 + 2HF↑is one of the materials used in the manufacture of the optical glass lens.
