Molecular formula：KF Molecular weight：58.10
Application：It is mainly used as a welding aid for various metals and alloys. It is widely used as a fluorinating agent in the production of organic compounds. It is used in agriculture to produce sodium fluoroacetate and fluoroacetamide insecticides. It is used in medicine to make norfloxacin. It can be used as an absorbent (absorbing HF and moisture). It is also a raw material for the preparation of potassium hydrogen fluoride. It can also be used for glass engraving and food preservation, as well as in the electronics industry.
Property：Colorless cubic crystal, easy to deliquesce, soluble in water, soluble in hydrofluoric acid and liquid ammonia, slightly soluble in alcohol and acetone, its aqueous solution is alkaline reaction, can corrode glass and ceramics, only when heated to sublimation temperature Decomposed, but the molten potassium fluoride is more active and can corrode refractory substances. Toxic, should be stored in a sealed state. The specific gravity is 2.48 and the melting point is 858 °C.
