Abstract

An electrode having good conductivity, low oxygen and chlorine overvoltage and a low corrosion rate under electrolysis conditions comprises an electrically conductive substrate made of or clad with a material eg valve metal or alloy resistant to the electrolyte and the electrolytic products, coated on at least a portion of the surface thereof with a coating containing 30-70% by weight of an acid insoluble metal tungstate eg MnWO4, ZrWO4 or CoWO4, 15-60% by weight tantalum pentoxide and 5-15% by weight of a platinum group metal oxide. Alternatively, with an undercoat rich in platinum group metal oxide, eg made of mixed crystals containing Ta2O5 and RuO2, the top layer contains 30-90% MnWO4, 0-15% RuO2 and 5-65% Ta2O5.
