The Use of Aluminum Fluoride

Mainly used for aluminum smelting production to reduce melting point and improve electrolyte conductivity; Used as an inhibitor for side fermentation in alcohol production; It is also used as a flux and component of glaze for ceramic and enamel glazes; It can also be used as a flux for smelting non-ferrous metals.

At present, over 95% of industrial aluminum fluoride is used in the aluminum industry as an additive in cryolite alumina solution. It can not only compensate for the loss of alumina in the electrolyte, but also reduce the molecular ratio of the electrolyte, lower the initial crystallization temperature of the electrolyte, and control the thermal balance during the aluminum electrolysis process. It is an essential raw material in the aluminum electrolysis industry.
