ABSTRACT OF THE DISCLOSURE An electrode for use in the electrolysis of an aqueous solution of a metal halide, the electrode comprising an electri- cally conductive corrosion-resistant substrate and, formed there- on, a coating comprising: 50 to 95 mole % of platinum; and 5 to 50 mole % of tin oxide. Optionally the coating containing 5 to 50 mole % of tin oxide and cobalt oxide, wherein the tin oxide is present in an amount of at least 5 mole % and the cobalt oxide is present in an amount up to 20 mole %. A process for producing the above-described electrode is also disclosed. The electrode is particularly useful for the electrolysis of aqueous metal halide solutions at low concentrations and low temperatures.
