Abstract: This invention is an inert, non-consumed, anode for use in electrolytic production of aluminum from the ore, consisting of a plurality of parallel vertical wires, or rods, attached to a suspended support structure which is also connected to an electrical power source. The wires are made of a high-temperature corrosion-resistant alloy and are durably surface-coated with a noble metal such as platinum, typically deposited by the SCX sputter coating process. In operation the coated wires are immersed in a fused fluoride electrolyte bath at 900 C., but remain structurally intact at that temperature. Moreover, the catalytic noble-metal surface dissociates the oxides formed in the electrolysis, avoiding generation of greenhouse gases. To suit the dimensions of the electrolytic furnace, the inert anode can be expanded in the form of linear or circular modules of the coated wires or rods. The power consumption with the inert anode of the invention is half that with a carbon anode.
