ABSTRACT:
Aluminum is manufactured in a Hall-Heroult cell employing a non-consumable anode having a substantially flat working surface 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.
