Abstract

Perovskite-type LnFeO₃ (Ln=La, Sm, Dy) powders were prepared by thermal decomposition of cyanidebridged heteronuclear complexes and their gas sensing properties to C₃H₆ were investigated. As a result, it was found that SmFeO₃ has the highest sensitivities to C₃H₆ among the perovskite oxides examined. By adding a small amount of Pd to SmFeO₃, gas-sensing properties such as gas sensitivity and response time were largely enhanced.
