      Granular cryolite

        
      Alias: Sodium hexafluoroaluminate; Sodium aluminum fluoride
      Molecular formula: Na3AlF6
      Grade: Industrial grade
      Appearance: granular
      Applications: Electrolytic aluminum, abrasive and grinding tool, glass, enamel, ceramics, pesticides
      CAS Number: 13775-53-6; 15096-52-3
      Colors: white, off-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. When using the new starting tank, it can make the electrolyte level stable and shrink slowly, which is conducive to the stable maintenance of electrolyte composition; the cathode absorbs sodium uniformly, which is beneficial to prolong the life of the electrolysis cell; the electrolysis temperature is reasonable, small changes, and easy to control; The volatilization loss is small, which can effectively improve the on-site operating conditions;
      2. It can save a lot of sodium fluoride or soda ash and reduce the production cost of electrolytic aluminum.
      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
