Cryolite, scientifically known as sodium hexafluoroaluminate or sodium aluminum fluoride, is a remarkable compound with a molecular formula of Na3AlF6. This pristine white fine crystalline substance is odorless and boasts greater solubility compared to natural cryolite. With a specific gravity of 3 and a hardness rating of 2~3, its melting point is a striking 1009 degrees Celsius. Though hygroscopic, Cryolite is predominantly utilized as a flux in aluminum electrolysis, offering wear-resistance as a filler in rubber and grinding wheels. Its versatility extends to serving as an enamel whitening agent, glass sunscreen, metal flux, and even an insecticide for crops. Embracing the Hall-Heroult method, Cryolite-based fluoride melt remains unparalleled as the solvent in producing metallic aluminum. Its unique set of indispensable properties has yet to find a worthy replacement.
