Abstract
In this paper, the ultrafine powders of the perovskite-type solid solution LaFe1−yCoyO3 (0≤y≤0.40) were prepared by chemical coprecipitation. The preparation conditions, phase constituents, conductance and gas-sensing properties were investigated. The results demonstrate that LaFe1−yCoyO3 is a p-type semiconducting material and it has high sensitivity and good selectivity to C2H5OH when y=0.20.
