ABSTRACT:
A non-consumable electrode having a substantially flat working surface suitable for use as an anode in molten salt electrolysis, particularly for the production of aluminum in Hall-Heroult reduction cells, is produced by a process wherein at least the portion of a conductive core that is exposed to the electrolyte bath is coated with a composition of higher resistivity than the core composition to provide uniform current density at all regions of the working surface of the anode.
