Zusammenfassung:Perovskite-type oxide, LaFeO3, was prepared from coordination polymer precursor, La[Fe(CN)6]·5H2O by calcination with the different two systems. In a muffle furnace system, the perovskite-type oxide was given by calcination at >500°C. The specific surface area of LaFeO3 powder calcined at 500°C for 24 h was 18 m2·g−1, which was the largest among single phase perovskite-type oxides calcined in a muffle furnace. In a gas-flow system, the perovskite-type oxide was given by calcination at significantly low temperature (>250°C). The specific surface area of LaFeO3 powder calcined at 300°C for 1 h in a gas-flow system was dependent on O2 partial pressure.
