ABSTRACT:
An inert anode50,for use in an electrolytic cell12for producing metals such as aluminum, is made by providing chemical source materials100such as at least two of metal salts, metal particles, or metal oxides and dissolving them to form a solution or a slurry110,followed by adding a base120and adjusting the pH so that a gel130is formed which is dried and calcined150, 160, 190to provide a blend of metal oxide powder200which can be pressed and sintered220to form an inert anode50.
