Cryolite - White And Pinkish Crystalline Powder, 80-325 Mesh Size Distribution | Slightly Soluble In Water, Low Loss On Ignition At Increased Molecular Ratios

These Cryolite is a white crystalline powder or a sandy-size granularity, and a pinkish crystalline powder or a sandy-size granularity as well.
Sp.gr.2.95a 3.01g/cm3, melting point about 1000 centigrade, specific heat 1.056j/gcentigradeat 18a 100centigrade.
Ita 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 800centigrade will appear 10.34%, 6.22% and 2.56% when the molecular ratio reaches 1.74, 2.14 and 2.63 reactively.
The size distribution can be sandy (80mesh), powder (200mesh, 325mesh), granular (0-10mm). Other items can be specified according to special requirement.
