WebSodium cryolite, also known as Na3AlF6, is a chemical compound composed of sodium, aluminum, and fluoride ions. It is a white, odorless powder that is highly soluble in water and has a melting point of 1000-1200 C. Sodium cryolite is used primarily in the production of aluminum metal. WebNov 19, 2024 · Cryolite is mainly used as a flux in the aluminum industry which can save more than 25% of energy consumption in the process of electrolytic aluminum smelting. Since the global production of natural cryolite is scarce and almost completely mined, most cryolite is produced artificially. Webtrations are known. The standard free energy of formation of cryolite calculated from solubility experiments is 745.4 ±1.0 kcal per mole at 25°C.
