Potassium Fluoroborate
Molecular formula:KBF4 Molecular weight:125.90
Usage: Used as an abrasive for thermosetting resin grinding wheels, a raw material for aluminum magnesium casting production of boron containing alloys, a flux for hot welding and brazing, a raw material for preparing boron trifluoride and other fluoride salts, an analytical reagent for electrochemical synthesis, etc. In addition, it is also used in low chromium chromium plating and lead tin alloy electrolytic solutions, as well as in welding and fusion plating, gold, stainless steel, etc.
Properties: white powder or gel crystal, no hygroscopicity. Bitter in taste, slightly soluble in water and hot ethanol, insoluble in cold ethanol and alkali, can be decomposed into boron trifluoride by strong acids such as sulfuric acid, and can melt with alkali metals and carbonates to form fluorides and borates. It begins to decompose during melting. Toxic!
