Refractory ceramics for aluminum electrolyzes based on clay raw material

Research output: Chapter in Book/Report/Conference proceeding › Conference contribution

Abstract

The results of integrated studies of clay raw material of the Siberian Region are considered and recommendations are issued for evaluation of the quality of materials, which make it possible to identify the means of control of the main technological properties of clay rocks with the aim of bringing then to the required level. The results of developing compositions and technologies for barrier materials based on the products of concentration of refractory clay for cathode lining in aluminum electrolyzes are described. High-density dry barrier mixtures with different Al₂O₃-SiO₂ 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).
