ABSTRACT:
A metallic electrode made of platinum, platinum iridium alloy, stainless steel, stainless steel alloys, titanium, titanium alloys, tantalum or tantalum alloys is coated with iridium oxide. Ir(III) trichloride is heated in 5.5M HCl until 75-80% of the solution is evaporated. Isopropyl or ethyl alcohol is added to the evaporated solution to restore the solution to its original volume. This restored acid/alcohol solution is aged for 1-2 weeks. The metallic electrode is soaked in the aged acid/alcohol solution for 16 hours, dried for one hour at room temperature and annealed in air at 320.degree. C. for 80-90 minutes.
