Calcium fluoride, also known as fluorite, has a wide range of uses. With the advancement of science and technology, its application prospects are becoming increasingly broad. The main uses of calcium fluoride are as follows:
metallurgical industry
Calcium fluoride is mainly used as a flux in the metallurgical industry. It can reduce the melting point of refractory materials, promote the flow of slag, and thus separate slag and metal well. During the smelting process, calcium fluoride also has the functions of desulfurization and dephosphorization, and can enhance the calcinability and tensile strength of metals. Therefore, it is widely used in steel smelting, ferroalloy production, iron smelting process, and non-ferrous metal smelting.
chemical industry
One important use of calcium fluoride in the chemical industry is the production of hydrofluoric acid. Hydrofluoric acid is produced by reacting acid grade fluorite (fluorite concentrate) with sulfuric acid in a heating furnace or tank. Hydrofluoric acid is a colorless liquid with a strong irritating odor and corrosiveness, and is a key raw material for producing various organic and inorganic fluorides and fluorine elements.
Building materials industry
Calcium fluoride is also widely used in the building materials industry, especially in industries such as glass, ceramics, and cement. In the glass industry, adding calcium fluoride as a flux and shading agent can promote the melting of glass raw materials. In cement production, the addition of calcium fluoride as a mineralizer can lower the sintering temperature of the furnace charge, reduce fuel consumption, enhance the viscosity of the clinker liquid phase during sintering, and promote the formation of tricalcium silicate. In the ceramic industry, calcium fluoride is mainly used as porcelain glaze, which can play a role in assisting color and melting in the production process of porcelain glaze.
In addition, high-purity calcium fluoride can also be used to make lenses. In drinking water, water containing 1-1.5ppm calcium fluoride can prevent and treat dental diseases.
