Abstract 1. THE METHOD OF PRODUCING AN ELECTRODE OF A VALVE METAL BASE FROM THE GROUP CONSISTING OF TITANIUM AND TANTALUM WHICH COMPRISES APPLYING A COATING MIXTURE IN LIQUID FORM TO SAID VALVE METAL BASE, WHICH ON HEATING FORMS AN OXIDE LAYER ON SAID BASE, 39.2% TO 78% OF WHICH COMPRISES AN OXIDE OF TITANIUM, 6.4% TO 47.45% OF WHICH COMPRISES AN OXIDE OF A PLATINUM GROUP METAL AND 1% TO 17.7% OF WHICH FORMS AN OXIDE OF A DOPING METAL FROM THE GROUP CONSISTING OF TIN, VANADIUM, LANTHANUM, COBALT, AND MIXTURES THEREOF, THE SAID PERCENTAGES BEING BASED UPON THE WEIGHT OF THE METALS IN SAID OXIDES, APPLYING SAID COATING IN SEVERAL SEPARATE LAYERS AND HEATING THE COATING ON THE VALVE METAL BASE BETWEEN THE APPLICATION OF EACH LAYER.
