Abstract:The oxygen sensors with limiting current derived from a dense diffusion barrier have an excellent advantage of detecting oxygen partial pressure by controlling the ratio of air and fuel in combustion environments. Therefore, AgNb 1−x Ti x O 3−δ (wherein x varies from 0.1 to 0.3) was prepared as such a dense diffusion barrier layer for sensor application. Among the investigated compositions as a new condensed barrier for the diffusion of sensors, AgNb 1−x Ti x O 3−δ (x = 0.1, 0.2, 0.3) exhibits oxygen ionic con… Show more
