Product Description

Fluorite, also known as fluorspar, has a chemical composition of CaF2, and its crystal is an isometric halide mineral. It emits blue or purple fluorescence under the irradiation of ultraviolet rays, cathode rays or heating, hence the name. The crystals often appear as cubic, octahedral or cubic interpenetrating twin crystals, and the aggregates are granular or massive. It is light green, light purple or colorless and transparent, sometimes showing rose red and white stripes, with a glass luster, and can be transparent to opaque. The octahedral cleavage is complete. The Mohs hardness is 4, and the specific gravity is 3.18.

Main Applications
 
1. Half of the world's fluorite production is used to produce HF, and then cryolite is developed for the aluminum smelting industry.
 
2. Fluorite is used as a coolant  in refrigerators.
 
3. In the glass industry, adding fluorite as a flux and a sunscreen agent can help melt the glass raw materials. The addition amount of fluorite varies for different glasses. For ordinary glass plates, the addition of fluorite is 1% of the charge; for alkaline glass balls, the addition of fluorite is 1% - 2%; for oxidized glass, the addition of fluorite is 3%; for white, cream - colored and colored glasses in the fluorite production process, in addition to acting as a co - solvent, it also acts as a sunscreen agent, and the added amount ranges from 10% to 20% of the charge. The glass industry has strict requirements for the quality of fluorite, requiring CaF2> 80% and Fe2O3 < 0.2%.
 
4. In cement production, fluorite is added as a mineralizer. Fluorite can reduce the sintering temperature of the charge, reduce fuel consumption, and at the same time increase the liquid phase viscosity of the clinker during sintering, promoting the formation of tricalcium silicate. In cement production, the addition amount of fluorite is usually 4% - 5% to 0.8% - 1%. The cement industry has no strict requirements for the quality of fluorite. Usually, the CaF2 content is above 40%, and there are no specific requirements for the content of impurities.
 
5. In the ceramic industry, fluorite is mainly used for enameling, and can play the role of color and flux in the production of enamel. For example, adding fluorite to red enamel can make the color bright and vivid. The addition amount of fluorite in ceramic enamel is generally about 10% - 20%.
