摘要： An electrode for use in an electrolytic reaction. The electrode has an electrically conductive base, preferably of a film-forming metal, the outside of which is a conductive material other than a film-forming metal, such as a layer of oxide of the base metal, and which is resistant to the electrolyte. At least a portion of the surface of said base has a coating of a mixed crystal material consisting essentially of at least one oxide of a filmforming metal and at least one oxide of a platinum group metal.

摘要： AN ELECTRODE FOR USE IN AN ELECTROLYTIC PROCESS HAVING A CONDUCTIVE BASE OF A MATERIAL WHICH AT LEAST ON THE OUTSIDE IS RESISTANT TO THE ELECTROLYTE AND THE PRODUCTS OF THE ELECTROLYSIS THEREOF, AND A COATING ON THE BASE WHICH CONSISTS ESSENTIALLY OF AT LEAST ONE OXIDE OF A FILM-FORMING METAL AND A NON-FILM-FORMING CONDUCTOR, THE TWO BEING IN A MIXED CRYSTAL FORM A COVERING AT LEAST 2% OF THE ACTIVE SURFACE OF THE BASE, AND METHODS OF MAKING THE ELECTRODE. THE RESULTING ELECTRODE IS ESPECIALLY USEFUL IN THE ELECTROLYTIC PRODUCTION OF CHLORINE AND ALKALI IN MERCURY CELLS, AND DIAPHRAGM CELLS, ELECTROLYTIC PRODUCTION OF CHLORATES, HYPROCHLORITES, PERSULPHATES, AND PERBORATES, OXIDATION OF ORGANIC COMPOUNDS, FUEL CELLS, DESALINATION AND PURIFICATION OF WATER, GALVANIC PROCESSES, AND AS AN ANODE IN CATHODIC PROTECTION SYSTEM, THE ELECTRODE HAVING A LONG LIFE, A LOW OVERVOLTAGE AND CATALYTIC PROPERTIES.
