From the perspective of chemical composition, fluorite is mainly composed of calcium fluoride (CaF2), which has strong stability and corrosion resistance. It is insoluble in water under normal conditions, but can react with dilute acid. This chemical property makes it an important cornerstone of the fluorine chemical industry. In the field of fluorine chemical industry, fluorite can react with sulfuric acid to produce hydrofluoric acid. As a basic chemical raw material, hydrofluoric acid is the key to the production of fluorine-containing polymers, refrigerants, fluorine-containing fine chemicals, etc., and is widely used in aerospace, electronics, automobile and other industries.

The physical properties of fluorite are also eye-catching. Its hardness is Mohs 4, and its relative density is between 3.175 and 3.184. It has a distinct glass luster. Common colors include green, blue, purple, yellow, etc., and even a crystal can appear in multiple colors. It is one of the most colorful minerals in nature. Moreover, some fluorites will emit blue or purple fluorescence when exposed to ultraviolet rays, cathode rays or heated. Some fluorites containing rare earth elements can continue to emit light for a period of time after the irradiation stops, which is phosphorescence. This characteristic makes it very useful in the field of optics and is used to manufacture optical lenses, phosphors, etc.

In industrial applications, fluorite plays an important role. In the metallurgical industry, it is a powerful assistant in steelmaking and ironmaking. It can reduce the melting point of slag, increase the fluidity of molten liquid, effectively remove harmful impurities such as sulfur and phosphorus, and improve the quality of metals. In the building materials industry, fluorite is added to cement production as a mineralizer to reduce the sintering temperature and achieve energy saving and consumption reduction. It can also be used to manufacture opalescent glass, ceramics, etc. to improve product performance.
