1. Mainly used as a raw material of fluorinated compounds, but also used in the manufacture of aluminum fluoride and cryolite, semiconductor surface etching and as a catalyst for alkylation 2. In the electronics industry used as a strong acid etchant, can be used with nitric acid, acetic acid, ammonia, hydrogen peroxide. 3.Uused as an analytical reagent, but also for the preparation of high purity fluoride. It is a necessary fluorine source for fluorine salts, fluorine refrigerants, fluorine plastics, fluorine rubber, fluorine medicine and pesticides 4. Is the production of refrigerant "freon", fluorine resin, organic fluoride and fluorine raw materials. It can be used as catalyst for alkylation, polymerization, condensation, isomerization and other organic synthesis in chemical production. It is also used to corrode the strata when mining some deposits, and to extract rare earth elements and radioactive elements. It is a raw material for the production of uranium hexafluoride in the atomic energy industry, and is also a raw material for the production of rocket fuel and additives, and can also be used to corrode glass and impregnate wood. 5. For the manufacture of organic or inorganic fluoride, such as fluorocarbons, sodium fluoride, aluminum fluoride, uranium hexafluoride and cryolite. It is also used in stainless steel, non-ferrous metal pickling, glass instrument calibration, glassware and mirror carving, engraving, and glassware polishing, frosted light bulb and general light bulb treatment, metal graphite milk silicon purification, metal casting sand removal, graphite ash removal, semiconductor (germanium, silicon) manufacturing. It is also used in dye synthesis. And other catalysts for organic synthesis. It is also used in electroplating, reagents, fermentation, ceramic treatment and the manufacture of fluorinated resins and flame retardants. 6. Used for etching glass, pickling metal, making inorganic fluorine salt products and chemical reagents. 7. Used in atomic energy industry, elemental fluorine, fluoride, can also be used as a catalyst, fluorinating agent for organic or inorganic fluoride manufacturing, also used in stainless steel, non-iron metal pickling, glassware frosting and pickling, frosted light bulb treatment.
