    325 / 200 Mesh Sodium Aluminum Fluoride Cryolite For Abrasives / Aluminum Industry

     

    Properties:

     

    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.


     

    Uses:

     

    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.
