Abstract
An electrode for electrochemical processes comprises a substrate of titanium or other valve metal, an intermediate protection layer based on valve metal oxides and a catalytic layer based on oxides of tin and of iridium doped with small amounts of oxides of elements selected between bismuth, antimony, tantalum and niobium. The electrode used in electrometallurgical processes, for example in the electrowinning of metals, as anode for anodic oxygen evolution presents a reduced overvoltage and a higher duration.
