Introducing Premium Cryolite, also recognized as sodium hexafluoroaluminate or sodium aluminum fluoride. With its molecular formula Na3AlF6, this pristine white, fine crystal is odorless and boasts a superior solubility compared to natural cryolite. It possesses a specific gravity of 3, a hardness rating of 2~3, and a melting point of 1009 degrees Celsius, making it notably easy to absorb moisture and thus get wet. Cryolite finds its versatility as a crucial flux in aluminum electrolysis, an exceptional wear-resistant filler for rubber and grinding wheels, an enamel whitening agent, a protective glass sunscreen, a robust metal flux, and even as an effective insecticide for crops. The esteemed Hall-Heroult method utilizes a cryolite-based fluoride melt as a solvent to manufacture metallic aluminum. Remarkably, no alternative compound has been discovered to substitute cryolite owing to its indispensable and unique properties.
