What is cryolite


Cryolite, with the chemical formula Na3AlF6, is a rare white fine crystalline mineral that has been discovered in the Ivitut large deposit on the west coast of Greenland. The main component of cryolite is sodium hexafluoroaluminate, which has stable chemical properties and is slightly soluble in water. In the molten state, cryolite can dissolve aluminum oxide, so it is used as a flux in the electrolytic aluminum industry. In addition, cryolite is widely used as a sunshade in the production of milky white glass and enamel products.
