新型致密扩散障极限电流氧传感器的制备及其性能
Preparation and Propeties of New Dense Diffusion Barrier Limiting Current Oxygen Sensor
摘要
Abstract
The NiO powder was synthesized by solid phase method. According to the results of X-ray diffraction and scanning electron microscopy, the mixture of NiO and 3Y20A with mass ratio 1:1 was prepared as the mixed ion-electron conductor. A limiting current oxygen sensor using 8YSZ (8% (mole fraction) yttira stabilized zirconia) as solid electrolyte layer and the mixed ion-electron conductor as dense diffusion barrier was developed successfully via a Pt liquid agglutination method. And the properties of the sensor were tested. The results indicate that the sensor has a good oxygen measurement characteristic at 923 K and 973 K with oxygen concentration varying from 1% to 40%. It shows a good linear relationship between the limiting current of sensor and oxygen concentration when oxygen concentration was in the range of 1%-25%. The response time curves show that the sensor has good repeatability and fast response time at different oxygen concentrations.关键词
