Properties: The product is a white crystalline powder or a sandy-size granularity, and a pinkish crystalline powder or a sandy-size granularity as well. Sp.gr. 2.95-3.01g/cm3, melting point about 1000 °C, specific heat 1.056j/g °C at 18-100 °C. It's slightly soluble in water, but insoluble in anhydrous . The content of its crystal water will be decreased while the increasing of the molecular ratio, therefore its loss on ignition will be also decreased while the increasing of the molecular ratio. After the paste of synthetic cryolite with different molecular ratio dehydrates, the loss on ignition at 800 °C will appear 10.34%, 6.22% and 2.56% when the molecular ratio reaches 1.74, 2.14 and 2.63 reactively.

Uses: It's mainly used as a flux in the aluminum smelting by fused-salt electrolysis; also an opalizer in the manufacture of enamel; an opacifier and auxiliary 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.

Packing: In plastic coating woven bags with Plastic Film bag and paper bags inside, Net wt 40Kg, 50Kg or 1000Kg, or as the requirement of clients.
