Fluorite, also known as fluorspar, is the crystal of CaF2, the main source of chemical elemental fluorine. Because of the unique chemical nature of fluorine atoms, it is difficult to be replaced by other substances. Today, fluorite and its industrial products applications include new energy, new materials, national defense, electronics, metallurgy, chemical, atomic energy, building materials, medicine, pesticides and many other traditional industries and emerging industries. Therefore, fluorite is called “the second rare earth” in the industry.
In metallurgy, fluorite powder can be used as a fluxing agent in black and non-ferrous metal smelting. In the steel industry, fluorite powder has the function of reducing the melting point of refractory substances, promoting the flow of slag, and achieving the separation of slag and metal.
In the field of chemistry, fluorite is the main raw material for the production of anhydrous hydrofluoric acid, and the basic raw material for the production of fluorine chemical products.
Fluorite can be used as a mineralizer for the production of cement clinker, which reduces the sintering temperature and saves energy. It also enhances the liquid viscosity of clinker during sintering.
As a ceramic ingredient, fluorite can be used as a flux and opacifier in the process of making ceramics and enamels, reducing the firing temperature and melt viscosity, improving the quality of the body and glaze, and is also an indispensable part of the preparation of the glaze.
High-purity hydrofluoric acid, which is made of fluorite, is a strong acid cleaning and corrosive agent used in the cleaning and corrosion of integrated circuits and VLSI chips. It is one of the key basic chemical materials for the development of the microelectronics industry.
In addition to the above-mentioned fields, fluorine-containing compounds prepared from fluorite can be also used in many industries such as new energy, national defense, medicine etc. With the advancement of science and technology, the application prospects of fluorite and its chemical products will continue to expand.
