） Abstract： Mixed electronic and oxygen ion-conduction solid diffusion barrier LaCaMnO3 was prepared by high-temperature solid-phase synthesis
Yttria (8％ in molar fraction) stabilized zirconia (YSZ) with high density (ρ>5
8g/cm3) and high conductivity(σ>10-2s/cm) was fabricated by chemical coprecipitation method
Experimental results show that the complex oxygen sensors obtain excellent and stable limiting current platform characteristics from 0％ oxygen concentration to ambient air oxygen partial pressure, and the magnitude of limiting current was in a exponential relation with the concentration of oxygen gas at 650 to 750 ℃
The new type sensors with simpler planar structure, faster time response and lower cost can be manufactured for the practical application
