Analytical reagent, fusing agent, in manufacture of Boron trifluoride, mould material for casting Al and Mg, in electrochemical and chemical experiments.

 

 

3. Potassium Fluoroborate (KBF4):


White powder crystal salt material.
It is a key ingredient in grain refining salts for aluminum, and can be used separately or combined with Potassium Fluotitanate to form a grain refining or ALTIB grain refine.
It is also used as a cleansing flux for nonferrous metals like aluminium and magnesium.
It can be uesed as an ingredient in welding, brazing, and soldering fluxes as well.
It is also used as active filler in abrasive products.
