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.2.953.01g/cm3, melting
point about 1000C, specific heat 1.056j/gC at 18100C. Its 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
800C will appear 10.34%, 6.22% and 2.56% when the molecular ratio reaches
1.74, 2.14 and 2.63 reactively.
Uses:
Its 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.
