Molecular weight：58.10
Property ：Colorless cubic crystal, easy to delixolysis, 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, heating to sublimation temperature only a little decomposition, but the melting of potassium fluoride is more active, can corrode refractory substances.Toxic, should be sealed storage.Melting point is 858 ℃.
Application ：Used for glass carving, food anticorrosion, electroplating, etc., also used as welding flux, insecticide, fluoride agent, absorbent.
Pack:It is packed in 25kg plastic woven bag or composite kraft paper bag, carton or cardboard bucket.
