Properties

 

Synthetic Cryolite is a white crystalline powder or a sandy-size granularity, and a pinkish crystalline powder or a sandy-size ranularity as well. Sp.gr.2.95—3.01g/cm3, melting point about 1000centigrade, specific heat 1.056j/gcentigradeat 18—100centigrade. It’s slightly soluble in water, but insoluble in anhydrous hydrogen fluoride. 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 800centigrade 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.
