摘　　要：采用共沉淀方法制备YSZ粉料,经低温(1300℃)烧结,得到圆片状YSZ烧结体(Y_2O_3含量8mol%),采用热分解法涂制铂电极,采用新颖的热辐射压封法实现电解质圆片与Al_2O_3管封接,制成了氧浓差电池,测量了固体电解质的密度、电导率以及不同温度、不同氧分压、不同氧流量下浓差电池的电动势,通过电势一氧分压关系曲线和电势-氧流量曲线的实验测量,得到了与固体电解质电质、气体渗透性相关的参数。YSZ disc bodies is obtained by sintering fine powder coprecipitated at low temperature 1570K. The Pt electrode and Pt leads are welded on YSZ disc by decomposition of H_2PtCl_6·8H_2O at 1073K. A new convenient radiation heat-press technique was adopted to seal the YSZ disc and Pt electrodes onto Al_2O_3 tube, then Y-ZrO_2 electrolyte oxgen sensor was obtained. The various performances of this sensor were measured. The results show that Y-ZrO_2 oxygen sensors exhibit a good EMF output performence.
