摘要： A METHOD OF MAKING A COATED ELECTRODE FOR USE IN AN ELECTROLYTE, THE ELECTRODE MADE THEREBY, AND THE METHOD OF USING THE ELECTRODE. AT LEAST PART OF THE SURFACE OF A CONDUCTIVE BASE CORREPONDING TO THE WORKING AREA OF THE ELECTRODE IS COATED AT LEAST ONCCE WITH A SOLVENT -CONTAINING COMPOSITION OF AT LEAST ONE MATERIAL FROM WHICH AN OXIDE OF A FILM-FORMING METAL CAN BE FORMED BY EVAPORATION AND HEATING AND AT LEAST ONE FURTHER MATERIAL FROM WHICH AT LEAST ONE NON-FILM FORMING CONDUCTOR CAN BE FORMED BY EVAPORATION AND HEATING. THE BASE HAS AT LEAST

THE OUTER SURFACE PORTION THEREOF CORRESPONDING TO THE WORKING AREA OF THE ELECTRODE MADE OF A CONDUCTOR RESISTANT TO THE ELECTROLYTE IN WHICH THE ELECTRODE IS TO BE USED. THE SOLVENT OF SAID SOLUTION IS EVAPORATED, AND THE RESIDUE REMAINING ON SAID BASE AFTER EVAPORATION IS HEATED TO DEPOSIT AN ELECTRICALLY CONDUCTIVE COATING ON THE ELECTRODE, WHICH COATING WILL TRANSFER ELECTRICAL ENERGY BETWEEN THE ELECTROLYTE AND THE ELECTRODE. THE ELECTRODE IS USED IN VARIOUS ELECTROLYTIC PROCESSES.

摘要： 1. A METHOD OF MAKING AN ELECTODE FOR USE IN AN ELECTROYLTE COMPRISING THE STEPS OF PLACING AT LEAST A PART OF THE SURFACE OF AN ELECTRICALLY CONDUCTIVE BASE CORRESPONDING TO THE WORKING AREA OF THE ELECTRODE IN AN ELECTROLYTE HAVING THEREIN AT LEAST ONE DISSOLVED SALT OF A FILM FORMING METAL AND AT LEAST ONE FURTHER DISSOLVED SALT OF A METAL OTHER THAN A FILM FORMING METAL TAKEN FROM THE GROUP CONSISTING OF GOLD, SILVER, PLATINUM, PALLADIUM, IRIDIUM, RUTHENIUM, OSMIUM, RHODIUM, IRON, NICKEL, CHROMIUM, COPPER, LEAD AND MANGANESE WHICH WILL DEPOSIT ANODICALLY AN ELECTRICALLY CONDUCTIVE OXIDE DURING ELECTROLYSIS, THE BASE HAVING AT LEAST THE OUTER SURFACE PORTION THEREOF CORRESPONDING TO THE WORKING AREA OF THE ELECTRODE MADE OF AN ELECTRICALLY CONDUCTIVE OXIDE DURING ELECELECTROLYTE IN WHICH THE ELECTRODE IS TO BE USED, PASSING A CURRENT THROUGH THE ELECTROLYTE AND THE ELECTRODE FOR DEPOSITING ON SAID PART OF THE SURFACE OF THE ELECTRODE A MIXED MATERIAL OF AN OXIDE OF A FILM FORMING METAL AND AN ELECTRICALLY CONDUCTIVE OXIDE OF THE METAL OTHER THAN A FILM FORMING METAL, AND HEATING THE THUS TREATED ELECTRODE AT A TEMPERATURE OF FROM 200 TO 600*C. FOR A TIME OF AT LEAST 5 MIN.

摘要： AN ELECTRODE FOR USE IN AN ELECTROLYTIC PROCESS. THE ELECTRODE HAS A CORE OF A FILM-FORMING METAL AND A LAYER HAVING AT LEAST THE OUTSIDE PORTION OF THE THICKNESS THEREOF OF AN ELECTTOLYTE RESISTANT AND ELECTROLYSIS PRODUCT RESISTANT MATERIAL, WHICH OUTSIDE PORTION HAS A THICKNESS OF AT LEAST ABOUT 0.054 MICRON. THE LAYER IS ON AT LEAST PART OF THE SURFACE OF SAID CORE. THE MATERIAL OF THE PORTION CONSISTS ESSENTIALLY OF AT LEAST ONE OXIDE WHICH IS AN OXIDE OF AT LEAST ONE PLATINUM METAL TAKEN FROM THE GROUP CONSISTING OF PLATINUM, IRIDIUM, RHODIUM, PALLADIUM, RUTHENIUM, AND OSMIUM. THE ELECTRODE IS ESPECIALLY USEFUL IN ELECTROLYSIS OF BRINE TO OBTAIN CHLORINE.
