Product Name: Aluminum Fluoride Alf3
Aluminium fluoride is an important additive for the production of aluminium by electrolysis. Together with Cryolite, it lowers the melting point to below 1000 째C and increases the conductivity of the solution. It is into this molten salt that aluminium oxide is dissolved and then electrolyzed to give bulk Al metal.

1.Mainly used in aluminum production, in order to reduce the melting point and improve the conductivity of the electrolyte.
2.Used as fermentation inhibitors in the production of alcohol.
3.Used as fluxing agent in the production of ceramic glaze and porcelain enamel glaze
and the glaze composition.
4.Used as flux smelting in producing non-ferrous metal.
