Potassium Fluoride

Molecular formula: KF          Molecular weight: 58.10
Uses: Mainly used for all kinds of metal, alloy welding flux, widely used as a fluorinating agent in organic compounds in the production, for the production of sodium fluoroacetate and agricultural insecticide fluoroacetamide medicine, used for norfloxacin, it can be used as absorbent (HF and water), it is also preparing potassium hydrogen fluoride materials, also can be used for glass carving and food preservation and the application in the electronics industry.
Properties:Colorless cubic crystal, easy deliquescence, soluble in water, soluble in hydrofluoric acid and ammonia, slightly soluble in alcohol and acetone, the aqueous alkaline reaction, the corrosion of glass and ceramics, only a little heated to decomposition sublimation temperature, but the molten potassium fluoride activity greatly, can corrode the refractory matter. Toxic and should be stored airtight. Specific gravity 2.48, melting point 858 DEG C.
CAS#:7778-23-3          Customs number:28261900          MSDS:YF0405-02          Dangerous regulation number:61513
