Product Name: cryolite

　　Molecular formula: Na3AlF6 molecular weight: 209.94 CAS No.: 13775-53-6

　　Physical and chemical properties: cryolite is a crystalline white powder. It is slightly soluble in water, with a density of 2.95 ~ 3.0 and a melting point of about 1000 ℃. It is easy to absorb water and moisture. It can be decomposed by strong acids such as sulfuric acid and hydrochloric acid to produce hydrofluoric acid and corresponding aluminum and sodium salts.

　　Function and application: it is mainly used as a cosolvent for aluminum electrolysis, and also as a wear-resistant additive for grinding products, which can effectively improve the wear resistance and cutting force of grinding wheel, and prolong the service life and storage time of grinding wheel; Flux for ferroalloy and boiling steel, nonferrous metal flux, casting deoxidizer, alkene polymerization catalyst; It is also used for glass antireflective coating, enamel opacifying agent, glass bleaching agent, flux of welding materials, filler in ceramic industry, resin, wear-resistant filler in rubber industry, pesticide, etc.

　　Packaging: woven bags lined with plastic bags, 25kg / 50kg each.
