摘要： An exhaust sensor includes a first sheet of ceramic that is perforated with a vent orifice and, a second sheet of ceramic that is laminated to the first sheet. A palladium circuit trace is positioned between the first sheet and the second sheet of ceramic and a fugitive ink is printed on one of the sheets that is in communication with the vent orifice and the palladium. The fugitive ink volatilizes during a firing process and created a void space that is occupied by a palladium oxide that forms at temperatures around 625-900C.

摘要： An exhaust sensor comprises a sensing electrode and a reference electrode each in contact with an electrolyte. At least one of the sensing electrode and the reference electrode are formed by depositing an electrode precursor material on an electrolyte precursor material and sintering the combination at a sufficient temperature for a sufficient time to achieve densification of the electrolyte, wherein the electrode precursor material comprises an alkali salt. Electrode patterns having enhanced perimeter ratios are also disclosed. The resulting exhaust sensor is capable of providing a usable output at a reduced operating temperature.

摘要： Disclosed herein is a gas sensor having a small amount of lead oxide incorporated into an inner electrode and an outer electrode, and a method for depositing the lead oxide. The lead oxide is applied in an amount sufficient to effectuate consistent performance during sensor break-in. Lead oxide is transferred to the electrodes of the sensor element during the fabrication process by exposing the sensor element to glass having a known lead content during a heating step. Lead oxide from the glass is vaporized and deposited on the electrodes in the form of lead oxide. The deposited lead oxide is incorporated into the electrodes of the sensor element. The lead oxide reduces performance irregularities thereby improving performance during the initial use of the gas sensor.
