Abstract
Carbon or carbon-based cathodes and cell bottoms of electrolytic cells for the production of aluminium in particular by the electrolysis of alumina in a molten halide electrolyte such as cryolite, are treated to better resist intercalation of sodium in the cell operating conditions by impregnation and/or coating with colloidal alumina ceria, cerium acetate, silica, alumina, lithia, yttria, thoria, zirconia, magnesia or monoaluminium phosphate followed by drying and heat treatment.
