ABSTRACT:
In the production of a metal such as aluminum by electrolysis of an electrolyte bath containing a compound of the metal dissolved therein to produce the metal at a graphite cathode surface, the wear rate of the graphite cathode surface is significantly reduced by incorporating therein selected amounts of certain compounds of aluminum or titanium, especially Al.sub.2 O.sub.3 and TiO.sub.2. The improvement is particularly suited to the production of aluminum from chloroaluminate electrolyte baths.
