Application of Synthetic Cryolite
Synthetic Cryolite (Sodium Aluminium Fluoride) is primarily used as a flux in the smelting or electrolytic production of aluminum .Thick size (0-10mm) and good fluidity, Convenient for mechanization and feeding automatically. It can be used to reduce the melting point of alumina and fast melting. In the friction industry, it is used as filler in bonded abrasives and in friction coated linings. It is also used in the glass and enamel industries.
