Molecular formula: KBF4
Molecular Weight: 125.91
Physical and chemical properties: White powder or gel crystallization, no hygroscopic, bitter taste, crystallization from aqueous solution can get six-sided prism crystal, relative density 2.50, melting point 530 "C, slightly soluble in water and hot ethanol insoluble in cold ethanol. Begins to decompose during melting. Can be decomposed by sulfuric acid and other strong acids to produce boron trifluoride. Fluoride and borate are produced when molten with alkali metal carbonate. Poisonous!
Product usage:
Used as a flux for hot welding and copper welding, aluminum magnesium is used to produce boron alloy raw materials, and in a heavy-duty grinding wheel with resin as abrasive binder as a filler. In Banyan and Banyan Silver Gold, stainless steel, can lift the dregs of light metal. Raw materials for the production of boron trifluoride and other fluorine salts.
It is also used in electrochemical processes and reagents.
