CAST CERMET ANODE FOR METAL OXIDE ELECTROLYTIC REDUCTION

摘要

The invention is a method for producing a cast cermet anode (32) for metal oxide electrolytic reduction by feeding metallic iron and metallic nickel in solid form to an oxidizing reactor (12); melting and oxidizing the iron and nickel and forming molten nickel ferrite; mixing the molten nickel ferrite with a base metal of high electrical conductivity such as nickel, copper, silver, or alloys thereof in a holding vessel (13) such as ladle or tundish, and casting the mixture into a mold to form a near net shape of the desired anode. Apparatus for carrying out the method, and the resulting product are also disclosed.
