Electrode and coating therefor
Abstract
Abstract 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.
