What types of dangerous goods does cryolite belong to?


Not a hazardous material. Cryolite is a mineral with the chemical formula Na3AlF6. It is a small white crystalline substance with no odor and a higher solubility than natural cryolite. It is used as a flux in the electrolytic aluminum industry and as a sunshade in the production of milky white glass and enamel. Cryolite, also known as sodium hexafluoroaluminate or sodium aluminum fluoride, has a molecular formula of Na3AlF6. It is a small white crystal with no odor, and has a higher solubility than natural cryolite. It has a specific gravity of 3, a hardness of 2-3, a melting point of 1009 degrees Celsius, and is prone to water absorption and moisture. Cryolite is mainly used as a flux for aluminum electrolysis, a wear-resistant filling agent for rubber and grinding wheels, an enamel whitening agent, a glass sunshade, and a metal flux.
