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.
Claims18
An electrical ceramic oxide device including
- a first body of an electrical ceramic oxide material;
- an electrical conductive lead means;
- and
- a second body of an interfacing material connecting said first body to said lead means, wherein said second body includes a first portion of material selected from the group consisting of ruthenium oxide, iridium oxide, osmium oxide, and rhodium oxide.
