Abstract

The corrosion chemistry of aluminosilicate potlining refractories has been studied using a post-mortem approach that considers both metallic sodium and molten bath as the corrosive agents. This article describes the results, which show that the cathode block material has a significant influence on the type of corrosion involved. Cells containing semi-graphitized cathode blocks are more susceptible to the attack of their refractory potlining by the action of the molten bath. The use of amorphous blocks in such cells promotes the corrosion of their potlining refractories mostly by the action of the metallic sodium.
