摘要：
Fe\-2O 3 /Al\-2O 3 nanocomposites prepared by using the sol-gel technique were reduced in H\-2 atmosphere at different temperatures, and the corresponding Fe/Al2O3 nanocomposites were obtained after the reduction of Fe\-2O 3 /Al\-2O 3 nanocomposites at 1173 K. The structures and properties of the specimens were studied by X-ray diffraction（XRD）, Mssbauer spectroscopy（MS）, and vibrating sample magnetometry（VSM）. The results show that the reduction temperature has a significant influence on the structure, the grain size, and the magnetic properties of the specimens.
