Abstract

The invention relates to non-consumable electrode hav­ ing a substantially flat working surface suitable for use as an anode in molten salt electrolysis, particularly for the produc­ tion 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 elecrolyte bath is coated with a compo­ sition of higher resistivity than the core composition to pro­ vide uniform current density at all regions of the working surface of the anode. The invention also relates to the produc­ tion of aluminum using such an electrode.
