Fluorite, also known as fluorite, is a kind of mineral, also known as soft crystal, colorful gem, rainbow gem, dream stone, etc. Its main component is calcium fluoride (CaF2), which contains more impurities. Fluorite in nature often shows bright color and lower hardness than knife. It can be used as a gem, a pearl at night, because most radioactive substances are usually harmful to human body.

purpose

1. Half of the world's Fluorite production is used to produce hydrofluoric acid, and then develop and manufacture cryolite, which is used in aluminum smelting industry, etc. The coolant (Freon) in the refrigerator should be fluorite.

2. Another important use of fluorite is to produce hydrofluoric acid. Hydrofluoric acid is produced by the reaction of acid grade fluorite (fluorite concentrate) and sulfuric acid in a heating furnace or tank. It is divided into anhydrous hydrofluoric acid and hydrohydrofluoric acid with water. They are colorless liquid, volatile, strong pungent smell and strong corrosiveness.

3. In the aluminum industry, hydrofluoric acid is used to produce aluminum fluoride, Artificial Cryolite, sodium fluoride and magnesium fluoride. In the aerospace industry, hydrofluoric acid is mainly used to produce jet liquid propellant and missile jet fuel propellant.

4. Hydrofluoric acid is the basic raw material of organic fluorine chemical industry. Through interaction with chloroform and carbon tetrachloride, hydrofluoric acid can produce fluorinated chlorocarbons and fluorocarbons with low toxicity and high chemical stability. It can be used as refrigerant, aerosol promoter, intermediate of solvent polymer and fluorocarbon resin and elastomer.

5. Hydrofluoric acid reacts with carbon tetrachloride to form Freon (usually expressed as f). Freon is not only used as a refrigerant, but also widely used in spray, extinguishing agent and fluoroplastics.

6. In medicine, fluoroorganic compounds can also be used to make fluoro anticancer drugs, fluorocortisone, fluorocarbon artificial blood, artificial heart and bone. In the inorganic fluorination industry, insecticides, preservatives, protective agents, additives, fluxes and antioxidants can be produced.

7. Fluorite is also widely used in glass, ceramics, cement and other building materials industry, and its consumption occupies the second place in China. In the glass industry, fluorite is added as a flux and sunscreen, which can promote the melting of glass raw materials.

8. In cement production, fluorite is added as mineralizer. Fluorite can reduce the sintering temperature and fuel consumption of the furnace charge, at the same time, it can enhance the liquid viscosity of the clinker during sintering and promote the formation of tricalcium silicate.

9. In the ceramic industry, fluorite is mainly used as glaze, which can play a role of assisting color and melting in the production process of glaze. If fluorite is added to the red glaze, the color will be bright and bright. Generally, the amount of fluorite in the glaze is about 10% - 20%. Also involved in the manufacture of enamel products.

10. Fluorite is also used in enamel industry and cast stone production. The amount of fluorite is 3% - 10% and 3% respectively.
