  • Figure 1: Schematic diagram of a zirconia oxygen sensor used to monitor automobile exhaust gases. The sensor, approximately the size of a spark plug, is fitted into the exhaust manifold of an automobile engine. The thimble-shaped zirconia sensor, sandwiched between thin layers of porous platinum, is exposed on its interior to outside air and on its exterior to exhaust gas passing through slits in the sensor shield. The two platinum surfaces serve as electrodes, conducting a voltage across the zirconia that varies according to the difference in oxygen content between the exhaust gas and the outside air.

    Inks are pulverized conductor and glaze particles dispersed in suitable organics, which impart the flow properties necessary for screen printing. On firing, the organics burn out as the glazes fuse. By varying the amount of conductor particles, it is possible to produce wide variations in…
