Title: Application of Mixture-microelectronic Technology on the Oxygen Sensors Based on Zirconia
Abstract: Oxygen sensors fabricated by thick-film, thin-film, and lamination technology decreased total impedance leading to the decreases of working temperature and reducing response time. Limiting-current-type gas sensors have been extended and used to detecte H2O, CO2, H2, CO, and HCs through measuring oxygen produced by electro-dissociation or catalytic reaction. Application of mixed ionic-electronic conductor membrane as diffusion-controlled layer improved sensing properties of amperometric sensor. In2O3, Y2O3-stabilized zirconia has can suppress the decrease of conductivity with aging as compared with Y2O3-stabilized zirconia. Trivalente cation-stabilized zirconia has been prepared using the high-energy ball milling technique.
