Abstract
An inert anode 50, for use in an electrolytic cell 12 for producing metals such as aluminum, is made by providing chemical source materials 100 such as at least two of metal salts, metal particles, or metal oxides and dissolving them to form a solution or a slurry 110, followed by adding a base 120 and adjusting the pH so that a gel 130 is formed which is dried and calcined 150, 160, 190 to provide a blend of metal oxide powder 200 which can be pressed and sintered 220 to form an inert anode 50.
