摘要：
Perovskite-type oxide, LaFeO3, was prepared from coordination polymer precursor, La[Fe(CN)(6)]center dot 5H(2)O by calcination with the different two systems. In a muffle furnace system, the perovskite-type oxide was given by calcination at >500 degrees C. The specific surface area of LaFeO3 powder calcined at 500 degrees C for 24 h was 18m(2).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 degrees C). The specific surface area of LaFeO3 powder calcined at 300 degrees C for 1 h in a gas-flow system was dependent on O-2 partial pressure. (C)2016 The Ceramic Society of Japan. All rights reserved.
