Potassium Fluoride

Molecular formula: KF          Molecular weight : 58.10

Uses: For a variety of metal, alloy welding flux, used as a fluorinating agent in the production of a range of organic compounds for the production of sodium fluoroacetate Fluoroacetamide pesticides in agriculture, medicine used to the system norfloxacin, itcan be used as a absorbent (absorption of HF and water), it is also the preparation of hydrogen fluoride, potassium raw materials, can also be used for glass engraving and food anti-corrosion, as well as used in the electronics industry.
Property:Colorless cubic crystal, easy deliquescence, soluble in water, soluble in hydrofluoric acid and liquid ammonia, slightly soluble in alcohol and acetone, the water on solvent alkaline reaction, can corrode glass and ceramics, heated to sublimation temperature whenlittle decomposition of molten Potassium fluoride activity can corrode the refractory material. Toxic and should be sealed storage. Specific gravity 2.48, Melting point 858℃.
