The difference between aluminum fluoride and cryolite

Different fluoride salts in the electrolytic aluminum plant smelter has different efficacy, generally all reduce the electrolyte solution primary crystal temperature, enhance the electrolyte solution composition. For example, magnesium fluoride, aluminum fluoride can separate out the carbon slag and enhance the electrolyte solution conductivity. When the molecular structure is relatively high, add aluminum fluoride to adjust many aspects. When the molecular structure is low, add sodium fluoride or ammonium bicarbonate to adjust in many ways. Aluminum fluoride plus the way: aluminum fluoride should be added in the middle of the aluminum trioxide shell layer, that is, after the production and processing of the first layer of aluminum trioxide, aluminum fluoride will be evenly scattered on the thin shell, and then add thermal insulation material. The next time of production processing
