摘要： A planar device includes a heating circuit that is disposed between ceramic layers in a planar device and co-fired with the ceramic. The heating circuit material and geometry are controlled so as to provide a targeted resistance characteristic as a function of temperature that allows interchangeability in an engine management system that was designed for a heater circuit based on a material system that cannot be co-fired with the planar device.

摘要： A conductive co-fired body for an electrochemical cell for an exhaust sensor comprises zirconia, yttrium oxide, and alumina. The body comprises about 15 to about 30 weight % monoclinic phase zirconia. This produces an electrochemical cell having low impedance wherein the zirconia body and alumina body are co-fired. One method for manufacturing the electrochemical cell comprises combining zirconia, yttria, and alumina with solvent and dispersant to form a mixture. After, binder is added to the mixture which is then de-aired and cast onto a tape surface. The tape is dried, metallized, and laminated to an unfired alumina surface. The structure is then co-fired to form a body for said electrochemical cell.
