Cryolite: A high-performance industrial cutting material, also known as sodium hexafluoroaluminate or sodium aluminum fluoride, boasts the molecular formula Na3AlF6. This odorless, fine white crystal surpasses natural cryolite in solubility and possesses a specific gravity of 3, with hardness ranging from 2 to 3. With a melting point of 1009 degrees Celsius, it is prone to water absorption. Predominantly, cryolite serves as a crucial flux in aluminum electrolysis, an essential wear-resistant filler in rubber and grinding wheels, a remarkable enamel whitening agent, a sunscreen in glass, a vital metal flux, and an effective crop insecticide. The Hall-Heroult process intricately utilizes a cryolite-based fluoride melt as a solvent for aluminum production. No alternative compound to date matches cryolite's unique properties, underpinning its irreplaceability.
