Abstract：
A series of Fe2-xCrxO3 (x = 0, 0. 4, 0. 8, 1. 2, 1. 6, 2. 0) nanocrystalline solid solutions were prepared via chemical coprecipitation method and characterized by means of specific surface area, transmission electron microscopy (TEM) and powder X-ray diffraction (XRD). Singler-phase a-Fe2O3/Cr2O3 solid solutions with corundum structure are obtained within the experimental conditions. IR spectra of samples with various Fe/ Cr contents show that the vibration frequency and intensity of the IR bands gradually shift from the typical modes of a-Fe2O3 (x = 0) to those of a -Cr2O3 (x = 2. 0) with increasing Cr content.
