Cryolite

      
    Alias:  Sodium hexafluoroaluminate; Sodium aluminum fluoride
    Molecular formula:  Na3AlF6
    Grade:  Industrial grade
    Appearance:  powdery
    Applications:  Electrolytic aluminum, abrasive and grinding tool, glass, enamel, ceramics, pesticides
    CAS Number:  13775-53-6; 15096-52-3
    Colors:  white

    Uses: Mainly used as a flux for aluminum electrolysis; also used as a wear-resistant additive for grinding products, which can effectively improve the wear resistance, cutting, and cutting power of the grinding wheel, and extend the service life and storage time of the grinding wheel; ferroalloy and boiling steel flux, non-ferrous Metal flux, deoxidizer for casting, olefin polymerization catalyst, anti-reflective coating for glass, emulsifier for enamel, opalizer for glass, flux for solder, filler for ceramic industry, pesticide for pesticide, etc. Industry companies.
    Features:
    1. The molecular ratio is stable at 2.6~2.8.
    2. When the new start cell is used, the electrolyte level can be stabilized and the contraction slower, which is beneficial to the stable maintenance of the electrolyte composition; the cathode absorbs sodium uniformly, which is beneficial to prolong the life of the electrolytic cell; The electrolysis temperature is reasonable, the change is small, and it is easy to control; the volatilization loss is small, which can effectively improve the on-site operating conditions;
    3. The amount of sodium fluoride or soda ash can be greatly saved, and the production cost of electrolytic aluminum can be reduced.
    Packing specification: Laminated plastic woven bag lined with plastic film double-layer packaging, net weight of each bag is 25Kg, 50Kg, or according to customer requirements.
    Technical requirements: GB/T 4291-2007, GB/T 4291-2017
