Product Description

Calcium Fluoride With Cas 7789-75-5

Chemical formula CaF2. Colorless crystalline or white powder; Insoluble in water, slightly soluble in inorganic acids; Hydrofluoric acid is formed with hot concentrated sulfuric acid. Calcium fluoride was prepared by calcium carbonate acting with hydrofluoric acid or repeated treatment with concentrated hydrochloric acid or hydrofluoric acid. Calcium fluoride mineral in nature is fluorite or fluorite, usually in gray, yellow, green, purple and other colors, sometimes colorless, transparent, glassy luster, brittleness, significant fluorescence phenomenon. Very spring fluoride is used to make special lenses. Fluorite is mainly used as a flux for smelting metal. When drinking water contains 1-1.5 PPM of calcium fluoride, it can prevent and cure dental diseases.

Use
Metallurgical industry
Fluorite is can reduce the melting point of refractory material, promote the slag flow, make the slag and metal fine separation, desulphurization and dephosphorization during the process of smelting, reinforced metal can be calcined and tensile strength etc. Therefore, as a melting agent, it is widely used in steel smelting, ferroalloy production, ferrochemical process and non-ferrous metal smelting. [2]
The chemical industry
Another important use of fluorite is to produce hydrofluoric acid. Hydrofluoric acid is through acid grade fluorspar (fluorspar ore concentrate) react with sulfuric acid in the furnace or jar and produced, anhydrous hydrofluoric acid and hydrofluoric acid water, they are all a colorless liquid, volatile, have the exciting taste of intense and strong corrosion resistance. It is a key raw material for the production of various organic and inorganic fluoride and fluorine elements. [2]
Building materials industry
Fluorite is also widely used in glass, ceramics, cement and other building materials industries.
In the glass industry, fluorite is added as a flux and shader, which can promote the melting of glass materials. Fluorite is added as a mineralizing agent in cement production. Fluorite can reduce the sintering temperature of furnace material and reduce fuel consumption. It can also enhance the liquid viscosity of clinker during sintering and promote the formation of tricalcium silicate. In the ceramic industry, fluorite is mainly used as a ceramic glaze, which can play a role of color and melting in the production of porcelain glaze. Fluorite is also used in enamel industry and casting stone production. [2]
Other USES
With the improvement of people's standard of living, the demand for ornaments and crafts is increasing. Fluorite has dense structure, bright color and various, as the raw material of craft carving is valued by people
