Physical and chemical properties of Calcium Fluoride CaF2
First analyze its physical and chemical properties, Calcium Fluoride CaF2, the English name is (calcium fluoride), and the molecular formula is CaF2.
Physical properties: colorless crystal or white powder; melting point 1423°C, relative density 3.18.
Chemical properties: The color is mostly yellow, green, blue, purple or white and rose. It glows when heated. It dissolves in concentrated inorganic acid, and decomposes to release hydrogen fluoride. It is slightly soluble in dilute inorganic acid and almost insoluble in water.
Its main use: used as a dehydration or dehydrogenation catalyst in organic chemical reactions. It can be used to make ceramics in the ceramic industry and as a flux in the iron and steel industry. Pure products can be used as catalysts for dehydration and dehydrogenation reactions. Base materials for nuclear reactors. Metallurgical fluxes. High-purity Calcium Fluoride CaF2 is used to make special optical crystals and lenses. Carving. In the chemical industry, it is mainly used to manufacture hydrofluoric acid, and then use it as a raw material to manufacture organic and inorganic fluorine compounds.
