Discover the unparalleled benefits of Cryolite, scientifically identified as sodium hexafluoroaluminate or sodium aluminum fluoride. With the molecular formula Na3AlF6, this exceptional material forms a fine, white, and odorless crystal. It boasts greater solubility than its natural counterpart, a specific gravity of 3, and a hardness rating of 2 to 3. Remarkably, it melts at 1009 degrees Celsius and exhibits a propensity to absorb moisture. As a versatile component, Cryolite serves as a crucial flux in aluminum electrolysis, a durable filler for rubber and grinding wheels, an enamel whitening agent, a glass sunscreen, a pivotal metal flux, and even an effective crop insecticide. The Hall-Heroult method leverages a Cryolite-based fluoride melt as a solvent for producing metallic aluminum—a testament to its irreplaceable characteristics and unique attributes.
