Abstract
Electrodes composed of ruthenium, iridium, osmium, or rhodium and the electrically conductive oxides of these metals are particularly well-suited to use in electrical ceramic oxide devices because of the low resistivity of the oxides and the stability of the oxides under the processing conditions necessary to optimize performance of electrical ceramic oxide materials.
