ABSTRACT:
Stable anodes comprising iron oxide useful for the electrolytic production of metal such as aluminum are disclosed. The iron oxide may comprise Fe3O4, Fe2O3, FeO or a combination thereof. During the electrolytic aluminum production process, the anodes remain stable at a controlled bath temperature of the aluminum production cell and current density through the anodes is controlled. The iron oxide-containing anodes may be used to produce commercial purity aluminum.
