Abstract:
LAYERS OF AN OXIDE MIXTURE OF AT LEAST ONE PLATINUM METAL AND OXIDES OF THE ELEMENTS SILICON, TIN OR GERMANIUM ARE APPLIED TO A CORE OF AN ANODICALLYS TABLE MATERIAL FOR THE PRODUCTION OF ACTIVATED ELECTRODES. FOR THIS PURPOSE, SILICON, TIN OR GERMANIUM OR A COMPOUND THEREOF WITH THE PLATINUM METAL OR A COMPOUND THEREOF IS CONVERTED INTO OXIDIC COMPOUNDS AND THESE ARE FIXED ONTO THE SURFACE OF THE ANODICALLY STABLE MATERIAL OBY THERMAL TREATMENT.
Abstract:
In an electrolysis cell with anodes and cathodes which are provided with openings, the cathode chamber is separated from the anode chamber by a diaphragm. The latter consists of a porous layer of oxides or oxidic compounds of the elements of sub-group 4B of the periodic table, of aluminum, of the rare earths or of chromium. The diaphragm is applied to that side of one of the electrodes which faces the counter-electrode.
