High sodium molecular ratio Cryolite hexafluide for Metal flux


Cryolite Properties


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.


Cryolite Uses


It is mainly used as a flux in the aluminium 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 aluminium alloy casting; And in the
production of ferrous alloy and effervescing steel.
