Abstract

Abstract An electrode for electrochemical processes comprises an electrically conductive base topped with a layer of active compound composed of, wt %: ______________________________________ metal oxide from the platinum group 5-45 at least one metal oxide from the iron and manganese group 19-94.9 boron oxide 0.1-50 ______________________________________ A method of fabricating the electrode for electrochemical processes involves deposition of an active compound on an electrically conductive base, the steps comprised in the procedure being application thereto of a solution made up of a thermally decomposed boric compound, at least one thermally decomposed metal compound from the iron and manganese group, and at least one thermally decomposed metal compound from the platinum group, and thermal treatment of said base at a temperature of 360° to 500° C. Another method of fabricating the electrode for electrochemical processes involves deposition of an active compound on an electrically conductive base, the steps comprised in the procedure being application thereto of a first solution of a thermally decomposed metal compound from the platinum group, thermal treatment of said base at a temperature of 360°to 500° C., application thereto of a second solution made up of a thermally decomposed boric compound and at least one thermally decomposed metal compound from the iron and manganese group, and thermal treatment of said base at a temperature of 360° to 500° C.
