Potassium Fluoroborate
Molecular formula: KBF4 Molecular weight : 125.90
Uses: Used as a thermosetting resin grinding wheel, abrasive aluminum-magnesium casting raw materials for the production of boron alloy, heat welding and brazing flux, the preparation of boron trifluoride and other raw materials of fluoride, the electrochemical synthesis of analytical reagent, in addition, alsolow chromate chrome-plated Lead tin alloy electrolyte and welding and fusion-plated, gold, stainless steel.
Property:White, powder one or gelatinous crystal, without hygroscopicity. Bitter, slightly soluble in water and hot ethanol, insoluble in cold ethanol and alkali can be sulfuric acid, the acid decomposition of boron trifluoride, and alkali metal carbonate melt generated fluoride and borate. Specific gravity 2.505g/mL(25℃), Melting point 350℃, toxic！
