Cryolite, also referred to as sodium hexafluoroaluminate or sodium aluminum fluoride, is a white, fine crystal with an impressive molecular formula of Na3AlF6. This odorless compound boasts a higher solubility than natural cryolite, with a specific gravity of 3 and a hardness rating between 2 and 3. It melts at a high temperature of 1009 degrees Celsius and is prone to absorbing moisture. Cryolite serves critical roles across various industries: as a flux in aluminum electrolysis, a durable filler for rubber and grinding wheels, a whitening agent for enamel, a sunblocker for glass, a vital metal flux, and as an agricultural insecticide. In the renowned Hall-Heroult process, cryolite-based fluoride melt is the irreplaceable solvent for producing metallic aluminum, owing to its unique and vital properties that no other compound can match.
