Abstract

Surface morphology of perovskite-type oxide, LaFeO_3, prepared by thermal decomposition of Fe(III) La(III) heteronuclear coordination polymer, La [Fe(CN)_6]・nH_2O, was compared with those of LaFeO_3 obtained by two conventional preparation methods, solid-state reaction of Fe_2O_3 and La_2O_3 and pyrolysis of a co-precipitated {Fe(OH)_3+La(OH)_3} precursor. At 1273 K, the first method gave LaFeO_3 with submicrometer-sized pores being highly ordered. At the same temperature, the LaFeO_3 particles with various sizes from nano-to micrometer in diameter and the highly sintered LaFeO_3 were obtained by solid state reaction and co-precipitation method, respectively.
