Used as a flux in aluminum and magnesium refining to remove impurities and prevent oxidation during melting.

Commonly employed in electroplating baths, especially for tin and tin-lead alloy plating, where it improves conductivity and deposit uniformity.

Acts as a source of fluoride ions in the synthesis of other fluorides and in catalyst preparation.

Utilized in the production of boron-containing materials and in some brazing salts for joining metals.

Also found in certain types of soldering fluxes and as a stabilizer in chemical processes involving fluorine.
