Abstract

Det er beskrevet stabile anoder (50) omfattende jernoksid anvendbare for elektrolyttisk fremstilling av metall slik som aluminium (80). Jernoksidet kan omfatte Fe3O4, Fe2O3, FeO eller kombinasjoner av disse. Under den elektrolyttiske aluminiumfremstillingsprosessen forblir anodene (50) stabile ved en kontrollert badtemperatur i aluminiumproduksjonscellen og strømtettheten gjennom anodene (50) kontrolleres. De jernoksidinneholdende anodene (50) kan brukes for å fremstille kommersielt rent aluminium.
