Abstract

An inert electrode material is made by reacting at an elevated temperature a mixture preferably comprising iron oxide, at least one other metal oxide, copper and silver. The reaction produces a material having ceramic phase portions and alloy phase portions, wherein the alloy phase portions have copper-rich interior portions and silver-rich exterior portions. Inert anodes made with a reaction mixture containing copper and silver have lower wear rates than inert anodes made with copper and no silver.
