Effect of Preparation Techniques of LaFeO3 Perovskite-Type Oxide on Its Surface Morphologies
Surface morphology of perovskite-type oxide, LaFeO3, prepared by thermal decomposition of Fe (III) La (III) heteronuclear coordination polymer, La[Fe(CN)6] ? nH2O, was compared with those of LaFeO3 obtained by two conventional preparation methods, solid-state reaction of Fe2O3 and La2O3 and pyrolysi...

description | Surface morphology of perovskite-type oxide, LaFeO3, prepared by thermal decomposition of Fe (III) La (III) heteronuclear coordination polymer, La[Fe(CN)6] ? nH2O, was compared with those of LaFeO3 obtained by two conventional preparation methods, solid-state reaction of Fe2O3 and La2O3 and pyrolysis of a co-precipitated (Fe(OH)3+ La(OH)3] precursor. At 1273 K, the first method gave LaFeO3 with submicrometer-sized pores being highly ordered. At the same temperature, the LaFeO3 particles with various sizes from nano-to micrometer in diameter and the highly sintered LaFeO3 were obtained by solid state reaction and co-precipitation method, respectively. |
