摘　　要：极限电流型氧传感器,无参考气体,氧浓度范围广。由于极限电流型氧传感器需要在850℃以上的高温环境中工作,材料之间的热膨胀系数不匹配。本文综述了极限电流型氧传感器的电解质材料和致密障碍层材料,对极限电流型氧传感的发展趋势和需要解决的问题提出了建议。Limiting current type oxygen sensor,no reference gas,wide range of oxygen concentration.Because the limiting current type oxygen sensor needs to work in a high temperature environment above 850℃,the coefficient of thermal expansion between materials does not match.In this paper,the electrolyte materials and dense barrier layer materials of limiting current type oxygen sensor are reviewed,and the development trend of limiting current type oxygen sensor and the problems to be solved are proposed.

关 键 词：极限电流型氧传感器 固体电解质 致密扩散障层
