An inert anode for the electrolytic production of metals such as aluminum is disclosed. The inert anode includes a ceramic oxide material preferably made from NiO, Fe2O3, and CoO. The inert anode composition may be of the formula Ni x Fe2 y Co2O(3y+x+z)+-.delta., where x is from 0.15 to 0.99, y is from 0.0001 to 0.35, z is from 0.0001 to 0.45, and .delta. is from 0 to 0.3. The inert anode may optionally include other oxides and/or at least one metal phase, such as Cu, Ag, Pd, Pt, Au, Rh, Ru, Ir and/or Os. The Ni-Fe-Co-O ceramic material exhibits very low solubility in Hall cell baths used to produce aluminum.
