  • Methods of making gas sensors and sensors formed therefrom
    Patent number: 7244316
    Abstract: A two-step chemical treatment method for chemically conditioning a sensor element comprising an electrolyte in ionic communication with a first electrode and a second electrode is described. The method comprises treating at least a portion of a sensor element with a first solution comprising an inorganic base, a carbonate salt and an acid salt; heating the sensor element; treating at least a portion of the sensor element with a second solution comprising an inorganic base and a carbonate salt; and drying the sensor element. The gas sensors comprising the two-step treated sensor elements have reduced lean shift, green effect, sensor output amplitude drop, and the light-off time is improved.

  • Sensing element and method of making
    Publication number: 20060213772
    Abstract: A gas sensing element and method of making are provided. The gas sensing element can comprise calcined inorganic oxides that sequester contaminants in an exhaust stream. The calcined inorganic oxides provide sensors with improved performance, thereby eliminating post-sinter chemical and/or electrical conditioning.
