Abstract

Abstract: The precursors of LaFeO₃were prepared by cifrnle process and nanocrystals of LaFeO₃were synthesized by a solid phase reaction at 400-500℃ for 2 h. The nanocrystalline material of LaFeO₃was obtained at 0. 5 GPa. The characterization of the samples was carried out by XRD and TEM. The size of the crystals is about 12. 4 nm by TEM. The diffracted X-ray intensity of the compact sample was attributed to the contribution from the LaFeO₃nanocrystals and the interfaces.

Key words: Lanthanum ferrite, Nanocrystalline, Synthesis
