<p>An extended life anode, for operating at a high anodic potential for carrying out an electrochemical process esp. in acidic medium, consists of an internal metallic substrate (10) covered with an intermediate valve metal layer (20) and an external electrocatalytic material coating (30). The novelty is that (a) the substrate metal is copper, nickel, titanium or (opt. stainless) steel; (b) the valve metal is tantalum, niobium, hafnium, zirconium or titanium; and (c) the electrocatalytic material is a metal and/or metal oxide. Also claimed is a process for mfg. the above anode.</p> |
