CAS 15096-52-3: Cryolite

Description: Cryolite, with the chemical formula Na3AlF6, is a naturally occurring mineral and synthetic compound primarily composed of sodium, aluminum, and fluorine. It is characterized by its white to colorless appearance, although it can also exhibit shades of yellow, red, or blue due to impurities. Cryolite has a unique crystalline structure, typically forming in a hexagonal system, and is known for its low solubility in water. One of its most significant applications is in the aluminum industry, where it serves as a flux in the electrolytic reduction of aluminum oxide, lowering the melting point and enhancing the efficiency of the process. Additionally, cryolite has been used historically as a pesticide and in the production of certain glass and ceramics. Its chemical properties include the ability to form complexes with metal ions, which can influence various chemical reactions. However, due to its fluoride content, caution is advised in handling cryolite, as fluoride can be toxic in high concentrations.
