High Purity Sodium Hexafluoroaluminate Powder 200 Mesh 1025 Degree Metling Point


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.
