An application of (4YSZ)_0.93(Fe₂O₃)_0.07 in limiting current oxygen sensor.

ABSTRACT: (4YSZ)_0.93(Fe₂O₃)_0.07 and 9 mol% Y₂O₃ stabilized ZrO₂ (9YSZ) were synthesized by co-precipitation method and their crystalline structure, microstructure, electronic conductivity, total conductivity were characterized. A limiting current oxygen sensor was assembled with (4YSZ)_0.93(Fe₂O₃)_0.07 dense diffusion barrier and 9YSZ solid electrolyte by Pt sintered-paste method. Influences of temperature (T), oxygen concentration (x(O₂)) and water vapor pressure (p(H₂O)) on sensing characteristics of the limiting current oxygen sensor were investigated. The crystalline structure of (4YSZ)_0.93(Fe₂O₃)_0.07 and 9YSZ bel
