【Abstract】 Factors influencing the ZrO2 sensor are systematically discussed in the light of electrode,substrate and their interface.From the discussion on the micro-scopic system of the Oxygen electrode, the nature of the Oxygen-sensing by the ZrO2 sensor was revealed. In the description of electrode, electrode/substrate interface, the causes of electrode contamination, the confugerational change of the electrode as well as the electrode/substrate interface inter-diffussion and their effect on the performance of the sensor are elucidated.Finally, on the basis of the equivalence of the crystal boundary pbase and the seperating-out phase, the variation of micro-structure of ZrO2 substrate and its influence on the performances of the sensor are expounded.更多还原
