Uses : Generate hydrofluoric acid and hot concentrated sulfuric acid

Molecular Structure:

Product description: Crystal structure: belong to cubic system, in a cube, octahedron or dodecahedron. Colorless crystals or white powder, qingzhen stone contains impurities, slightly green or purple. When heated. Density of 3.18 g/cm 3, melting point 1402 ℃, boiling point 2497 ℃, the refractive index of 1.434. Low toxicity. Very difficult to soluble in water. Soluble in hydrochloric acid, hydrofluoric acid, sulfuric acid, nitric acid and ammonium salt solution, insoluble in acetone. Soluble in aluminum salt and iron salt solution to form complex, generate hydrofluoric acid and hot concentrated sulfuric acid. Calcium fluoride with concentrated sulfuric acid reaction can be obtained in the castle hydrogen fluoride. With a variety of metal oxide eutectic formed. Calcium fluoride application is very extensive, with the progress of science and technology, more and more wide prospect of application. Mainly used in metallurgy, chemical industry and building at present fluorite Three big industry, the second for light industry, optics, sculpture and the defense industry. According to the use requirements, therefore, at present our country fluorite mineral products mainly has four big series of varieties, namely the fluorite ore and fluorescent (CFC) stone concentration, optical, sculpture, fluorite and fluorite ore fines.
