For Ceramics/glazes Welding consumables Na3alf6 Sodium Synthetic Cryolite
Product description:
Cryolite is also known as sodium hexafluoroaluminate or sodium aluminum fluoride. Its molecular formula is Na3AlF6, white fine crystal, odorless, solubility is larger than natural cryolite, specific gravity is 3, hardness is 2~3, melting point is 1009 degrees Celsius, easy to absorb water. Get wet. Cryolite is mainly used as a flux for aluminum electrolysis, a wear-resistant filler for rubber and grinding wheels, an enamel whitening agent, a glass sunscreen and a metal flux, and an insecticide for crops. The Hall-Heroult method is a method in which a cryolite-based fluoride melt is used as a solvent to produce metallic aluminum. To date, no other compound has been found to replace cryolite. This is because cryolite has other indispensable properties beside
