Chemical type CaF2. Colorless crystalline or white powder; difficult to dissolve in water and slightly soluble in inorganic acids; hydrofluoric acid is produced with the effect of hot sulfuric acid. The general use of calcium carbonate with hydrofluoric acid or concentrated hydrochloric acid or hydrofluoric acid treatment repeatedly fluorite powder to prepare calcium fluoride. The nature of the calcium fluoride mineral fluorite or fluorite, often gray, yellow, green, purple and other colors, sometimes colorless, transparent, shiny glass, brittle, has a significant fluorescence phenomenon. Is used to make special lens spring fluorspar. Fluorite is mainly used as a flux of metal smelting; drinking water containing 1-1.5ppm calcium fluoride can prevent dental disease.

 

The calcium carbonate or calcium hydroxide dissolved with hydrofluoric acid, the concentration of the obtained solution, or to calcium salt solution with fluoride, calcium fluoride by colloidal precipitation can be refined by. General laboratory use calcium carbonate with hydrofluoric acid or concentrated hydrochloric acid and hydrofluoric acid treatment repeatedly fluorite powder to prepare calcium fluoride

 

Calcium fluoride is widely used, with the progress of science and technology, more and more broad prospects. At present, it is mainly used in three major industries of metallurgy, chemical industry and building materials, followed by light industry, optics, sculpture and national defense industry.
