Abstract

Abstract: The nanocrystals of spinel ZnFe₂O₄ and perovsldte-type LaFeO₃ were prepared by the stearicacid gel method. The monitoring of synthesis process and the characterization Of the structure andmorphology of the ultrafine particles were performed by the thermal gravimetric and differentialthemal analyzer(TG-DTA), X-ray powder diffraction (Xan), transmission electron microscope(TEM) and BET specific surfaCe area absorption metor.

Key words: nanocrystal, ZnFe₂O₄, LaFeO₃, the stearic acid gel method
