Cryolite, a remarkable compound also recognized by its chemical name sodium hexafluoroaluminate or sodium aluminum fluoride, is characterized by its molecular formula Na3AlF6. It presents as a white, fine crystalline material, devoid of any odor. Notably, it exhibits greater solubility than its natural counterpart. This compound boasts a specific gravity of 3, coupled with a hardness rating of 2~3, and melts at a temperature of 1009 degrees Celsius. Additionally, it is prone to water absorption, making it hygroscopic. Cryolite's range of applications is extensive; it serves primarily as a flux in aluminum electrolysis, enhancing efficiency in this process. Moreover, it is utilized as a wear-resistant filler in both rubber and grinding wheels, as a whitening agent in enamels, a sunscren in glass, a flux in metal processing, and also functions as an effective insecticide for agricultural crops. The Hall-Heroult method—a pivotal process in aluminum production—depends on a cryolite-based fluoride melt as a solvent to yield metallic aluminum. Its unique properties are irreplaceable, as no other compound has been found to match its capabilities.
