What are the main components of cryolite?

Cryolite a mineral, sodium hexafluoroaluminate. White fine crystals, no smell, solubility than natural cryolite, melting point 1009 degrees Celsius, easy to absorb water and moisture.

The physical properties of cryolite, molecular weight is 209.94, is a complex compound or complex salt, color is white due to impurities, off-white, yellow powder or crystalline particles, its melting point 1025 ℃, the bulk density is 0.6 ~ 1.0g/L, true density is 2.95 ~ 3.05g/cm3, heat of generation is 225KJ, specific gravity is 2.75 ~ 3.00g/cm3,. The heat of melting is 107KJ.

Cryolite is mainly used as flux for aluminum electrolysis, wear-resistant filler for rubber and grinding wheels, emulsion for enamel, glass shading agent and metal melting agent, insecticide for crops, etc.
