Perovskite-type LaFeO3 has been synthesized hydrothermally under Na2CO3-con
taining medium, and characterized by X-ray diffraction (XRD), SEM, IR and I
CP. The product corresponds to orthorhombic perovskite-type LaFeO3, with a
cubic habit over a small particle size range of 10-20 mu m. The LaFeO3 form
ation temperature decreased by about 150 degrees C by introducing carbonate
into the hydrothermal system. (C) 2000 Elsevier Science B.V. All rights re
