- Half of the world’s fluorspar production is used to manufacture hydrofluoric acid, and then develop the manufacture of cryolite for aluminum smelting industry. Use fluorspar as coolant (freon) in the refrigerator.
- Another important use of fluorspar is the production of hydrofluoric acid.Hydrofluoric acid is produced by the reaction of acid grade fluorspar (fluorspar concentrate) with sulfuric acid in the heating furnace or tank. It can be divided into anhydrous hydrofluoric acid and hydrofluoric acid with water. They are all colorless liquid, volatile, with strong stimulating smell and strong corrosive.
- In the aluminum industry, hydrofluoric acid is used to produce aluminum fluoride, artificial cryolite, sodium fluoride and magnesium fluoride.In aviation and aerospace industry, hydrofluoric acid is mainly used to produce liquid propellant for jet aircraft and missile jet fuel.
- Hydrofluoric acid is the basic raw materials of organic fluorine chemical industry, it through the interaction with chloroform and carbon tetrachloride, the production of small toxicity, high chemical stability of fluorinated chlorinated hydrocarbons and fluorocarbons, as refrigerant, air sol accelerator, solvent polymer intermediates and fluorocarbons resin and elastomer.
- Hydrofluoric acid reacts with carbon tetrachloride to produce Freon (usually expressed as F).Freon as a refrigerant, but also widely used in spray, fire extinguishing agent, fluoroplastics, etc.
- In medicine, fluoroorganic compounds can also make fluorinated anticancer drugs, fluorocortisone, fluorocarbon artificial blood, artificial hearts and bones.In the inorganic fluorine industry, insecticides, preservatives, protective agents, additives, fluxes and antioxidants can be produced.
- Fluorspar is also widely used in glass, ceramics, cement and other building materials industry, and its dosage ranks second in China.In the glass industry, fluorspar as a flux, sunscreen added, it can promote the melting of glass raw materials.
- In cement production, fluorspar is added as a mineralizer.Fluorspar can reduce the sintering temperature of the charge, reduce the fuel consumption, enhance the liquid viscosity of the clinker during sintering, and promote the formation of tricalcium silicate.
- In the ceramic industry, fluorspar is mainly used for glaze, it can play a role in the process of glaze production and fusion.For example, after adding fluorspar to the red enamel, the color and lustre are bright and bright. The amount of fluorspar added to the enamel in ceramic production is generally about 10% ~ 20%.They were also involved in the manufacture of enamel products.
- Fluorspar is also used in enamel industry and casting stone production, with the addition amount of 3% ~ 10% and 3%, respectively.
