Introduction:

Cryolite is a mineral, sodium hexafluoroaluminate (Na3AlF6), white monoclinic crystal system, slightly soluble in water, soluble in alumina, used as a flux in the electrolytic aluminum industry, and made of milky white glass in Chemicalbook and enamel opacifiers. It is often off-white, light yellow, light red or black due to impurities. Often inseparable dense block, with glass luster. Slightly soluble in water, the aqueous solution is acidic.

Use: 

Cryolite is mainly used as a flux for aluminum electrolysis; it is also used as a wear-resistant additive for grinding products, which can effectively improve the wear resistance, cutting and cutting force of the grinding wheel, prolong the service life and storage time of the grinding wheel; the flux of ferroalloy and boiling steel, non-ferrous Metal fluxes, casting deoxidizers, olefin polymerization catalysts, anti-reflective coatings for glass, emulsifiers for enamel, opalescent agents for glass, fluxes for welding materials, fillers for ceramics, insecticides for pesticides, etc. enterprise.
