|Name:||325mesh Cryolite Sodium Aluminum Hexafluoride CAS 13775-53-6 For Metal Surface Treatment||Formula:||Na3AlF6|
|CAS No:||15096-52-3;1344-75-8 13775-53-6||Density::||2.95-3.05g/l|

sodium aluminium fluoride,
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.
