Product Description
200 mesh cryolite sodium aluminum fluoride CAS 15096-
52-3 for flux
Sodium fluoroaluminate is a white crystalline powder or a sandysize 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 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 800° C will appear 10.34%, 6.22% and 2.56%
when the molecular ratio reaches 1.74, 2.14 and 2.63 reactively.

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.
