Summary

The linings of industrial alumina reduction cell cathodes have historically utilized layers of dense firebrick to protect the lower layers of low thermal conductivity material from the diffusion and deterioration of cryolitic salts. Refractory castables were evaluated as a possible monolithic barrier to protect the cathode insulation. The influence of several factors controlling the refractory resistance to cryolite has been investigated
