What is Calcium fluoride used for?

Calcium fluoride is used to manufacture optical components such as windows and lenses, used in thermal imaging systems, spectroscopy, telescopes, and excimer lasers. It is transparent over a broad range from ultraviolet (UV) to infrared (IR) frequencies.

Calcium fluoride has a wide range of uses, and with the advancement of science and technology, its application prospects are becoming wider and wider. At present, it is 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, there are currently four major series of fluorite mineral products in my country, namely fluorite lump ore, fluorite (fluorite) concentrate, fluorite powder, and optical and carved fluorite.

Metallurgical Industry:

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

chemical industry:

Another important use of fluorite is to produce hydrofluoric acid. Hydrofluoric acid is produced by the reaction of acid-grade fluorite (fluorite concentrate) with sulfuric acid in a heating 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.
