Synthetic Cryolite

Application

Synthetic Cryolite (Sodium Aluminium Fluoride) is primarily used as a flux in the smelting or electrolytic production of aluminium and can be used to reduce the melting point of alumina. In the friction industry, it is used as a filler in bonded abrasives and in friction coated linings. It is also used in the glass and enamel industries.

Packaging

Synthetic Cryolite is supplied as a dry powder in 25kg paper sacks.
