Preparation and Characterization of Nanocrystals ZnFe2O4 and LaFeO3
纳米晶铁酸锌和铁酸镧的合成与表征

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.
