Synthetic Cryolite, Na3AlF6, is a white monoclinic powder synthesized from hydrofluoric acid and soda, slightly soluble with fluxing at 1000°C for alumina dissolution in Hall-Héroult process per Sigma-Aldrich inorganics.
Synthetic Cryolite
In aluminum smelting electrolytes; in abrasive wheels for bonding; in insecticides as stomach poisons; in vitreous enamels; and in fireworks for green flames.
Fluoride ions release toxic skeletal fluorosis chronic. Aquatic persistent; use HF-resistant PPE and calcium gluconate for exposures.
Packaged in 50 kg fiber-reinforced plastic barrels. Store in fluoride-safe dry zones.
