Uses:

1. Cryolite is mainly used as the flux of aluminum smelting of molten salt.

2. Also used for enamel emulsion, sunscreen agent and solvent in the production of glass and enamel.

3. Insecticide on crops.

4. The flux of aluminum alloy casting, the production of ferroalloy and the production of rimmed steel and the wear-resisting filler of resin rubber.
