• Product description :

  　　We have the different types of cryolite used in different usage, appearance: like powder and sand , higher quality and lower quality.

  　　It’s mainly used as a flux in the aluminum smelting by fused-salt electrolysis; an opacifier andauxiliary solvent of glass and enamel; an insecticide of crops; a flux in aluminum alloy casting; and in the production of ferrous alloy and effervescing steel; as well as a wear-resistant filler for resin and rubber-boned abrasive wheels.
