Product Description

High quality sodium cryolite in China





Synthetic cryolite is usually made from sodium aluminate, sodium bicarbonate, and sodium fluoride. Cryolite may be obtained by (a) mining natural mineral cryolite or (b) synthesis by the reaction of aluminum oxide, sodium chloride and hydrogen fluoride.

Cryolite (Na3AlF6, trisodium hexafluoroaluminate) is an important raw material for the primary aluminium manufacturing. Cryolite is also consumed in the abrasives, ceramics and glass industries.
