Application
1.Aluminum smelting: Calcium fluoride as an additive to bauxite, can control the melting point and increase the yield of aluminum.
2.Metallurgical industry: Calcium fluoride can be used as a flux and slag in the steel and casting industry, which can effectively reduce the oxidation rate and melting point of metals.
3.Ceramics, glass and glazes: Calcium fluoride can be used as raw materials for ceramics and glass to increase their hardness and transparency, and in products such as glazes and reflective finish paints.
4.Chemical industry: Calcium fluoride is used in the production of chemicals such as fluoride and fluorocarbons.
5.Semiconductors, electronics, optics and pharmaceuticals: Calcium fluoride can also be used for material preparation in these fields.
6.Other fields: Calcium fluoride is also used in the manufacture of special lenses, fluorspar abrasives, and as a raw material for certain optical products.
7.Light, optical, engraving and defense industries: Calcium fluoride is also used in these industries.
1.8.Water treatment: Adding calcium fluoride to drinking water can help prevent dental disease, usually in concentrations of 1-1.5ppm.
