Uses Of Calcium Fluoride

Calcium Fluoride has a wide range of uses. With the advancement of science and technology, its application prospects are becoming wider and wider. Mainly used in the three major industries of metallurgy, chemical industry and building materials, followed by light industry, optics, sculpture and national defense industries. Therefore, according to the application requirements, my country's fluorite mineral products mainly have four series of varieties, namely fluorite lump ore, fluorite (fluorite) concentrate, fluorite powder, and optical and carved fluorite.

Fluorite has the characteristics of lowering the melting point of refractory substances, promoting the flow of slag, separating the slag and metal, desulfurizing and dephosphorizing during the smelting process, and enhancing the forgeability and tensile strength of the metal. Therefore, it is widely used as a fluxing agent in steel smelting and ferroalloy production, iron smelting process and non-ferrous metal smelting.

Another important use of fluorite is to produce hydrofluoric acid. Hydrofluoric acid is produced by reacting acid-grade fluorite (fluorite concentrate) with sulfuric acid in a furnace or tank. It is divided into anhydrous hydrofluoric acid and hydrofluoric acid. They are both a colorless liquid. , Volatile, strong irritating smell and strong corrosiveness. It is the key raw material for the production of various organic and inorganic fluorides and fluorine elements.

In the glass industry, fluorite is added as a flux and sunscreen agent, which can promote the melting of glass raw materials; in cement production, fluorite is added as a mineralizer. Fluorite can reduce the sintering temperature of the furnace charge, reduce fuel consumption, and at the same time enhance the liquid viscosity of the clinker during sintering, and promote the formation of tricalcium silicate; in the ceramic industry, fluorite is mainly used as enamel, which can be used in the production of enamel. In the process, it plays a role in color and flux; fluorite is also used in the enamel industry and cast stone production.

With the improvement of people's living standards, the demand for ornaments and handicrafts continues to increase. Fluorite has a dense structure, bright and diverse colors, and is valued by people as a raw material for craft carving
