Sodium Fluoroaluminate

Sodium fluoroaluminate, commonly known as cryolite. The pure product is a colorless transparent crystal. Relative density of 2.9-3.O, melting point of 1000 ℃. Easy to absorb water and moisture, soluble in water. The aqueous solution is acidic and will decompose hydrogen fluoride gas when encountering sulfuric acid! Sodium fluoroaluminate is mainly used as a fluxing agent for aluminum smelting, an
