    Phase evolution, microstructure, and gas-sensing characteristics of the Sb2O3–Fe2O3 system prepared by coprecipitation

    Precursor powders with antimony-to-iron (Sb/Fe) atomic ratios ranging from 0 to 2.0 were prepared by chemical coprecipitation. The origin of enhanced gas-sensing behavior at a higher calcining temperature was ...
