325mesh cryolite Sodium aluminum hexafluoride CAS 13775-

53-6 for metal surface treatment

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.
