Abstract

The authors describe the results of developing compositions and technologies for barrier materials based on the products of concentration of kaolins from the Kampanovskii deposit for cathode lining in aluminum electrolyzes. High-density dry barrier mixtures with different Al 2O-SiO 2 ratios (from 0.42 to 0.76) have been obtained, which can be used in two-layer linings for aluminum electrolyzers (in the high-alumina and silica layers). The composition and properties of these mixtures correspond to known foreign analogs.
