More Information
Summary:A cermet inert anode for the electrolytic production of metals such as aluminum is disclosed. The cermet inert anode composition for use in a molten salt bath comprises: a ceramic phase; and a metal phase comprising at least one base metal selected from the group consisting of Cu and Ag, and at least one noble metal selected from the group consisting of Ag, Pd, Pt, Au, Rh, Ru, Ir and Os. The cermet inert anodes may be used in electrolytic reduction cells for the production of commercial purity aluminum as well as other metals.
