Abstract
The invention is a method for producing a cast ceramic anode for metal oxide electrolytic reduction by feeding metallic iron and metallic nickel in solid form to an oxidizing reactor; melting and oxidizing the iron and nickel and forming molten nickel ferrite; mixing the molten nickel ferrite with dopant in a holding vessel such as ladle or tundish to increase electrical conductivity of the mixture, 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.
