Anti-oxidation coating for carbon anode in aluminum electrolysis was studied in this paper. Different compounds of the anti-oxidation coating had different effects on carbon anode. The results showed that hot weight loss rate of coated anode was lower 10–30% than that of uncovered anode. The compounds of the anti-oxidation coating were optimized by SEM and tests of hot weight loss. It was proved that the anti-oxidation coating had great inoxidizable effects on carbon anode, and it was no influence on normal aluminum electrolysis.
