Y-, Fe co-doped CaZrO3 (Y0.08Ca0.92Zr1-xFexO3-δ (x=0.3, 0.4, 0.5)) was synthesized by solid state reaction method. The crystal phase composition, microstructure, oxygen ionic conductivity, total conductivity and sensing properties were investigated. The result suggests that a highly orthorhombic perovskite structure and the increase of Fe-doped amount is unfavorable for the formation of single orthorhombic perovskite structre. The total electrical conductivity and ionic conductivity increase with Fe-doped amount increasing. The oxygen sensor shows good limiting current plateau in the range of 800-950 ℃. The linear relationship between limiting current (lgIL) and 1 000/T can described as follows: lgIL =3.215-2.101 3×(1 000/T)and the activation energy of oxygen ion is 0.417 eV. At 750 ℃、1.0%≤x(O2)≤7.5%, the relationship between limiting current (IL) and oxygen amount (x(O2)) can be expressed: IL= 7.047 6+3.875 1×x(O2).
