Abstract

La0.9Sr0.1Ga0.8Mg0.2O2.85 (LSGM9182) was used to make the amperometric oxygen sensor with a density diffusion barrier. The material of the density diffusion barrier and solid electrolyte are all LSGM9182.The sensor was tested in the atmosphere of O2 and N2 at 873K, 923K and 973K, respectively. From the tested data, it could find out that this sensor presents the favourable limiting current platforms, and the limiting current exhibited a linear dependence on oxygen concentration. Also the response time was tested. The rising time was 10-15s and the falling time was 15-20s.
