 Abstract: alpha-Fe2O3 nanoparticles were prepared by the sol-gel process with ethylene oxide (EO) and FeCl3 as starting materials. The influences of the molar ratio of EO to Cl-, the concentration of FeCl3, the volume percentage of ethanol and heat treatment on the structural properties of the alpha-Fe2O3 nanoparticles were investigated by XRD, TEM and SAXS (small angle X-ray scattering) techniques. It was found that the mean size of the alpha-Fe2O3 nanoparticles formed via the sol-gel process is smaller than those formed via the sol process. The values of the mass fractal dimension (D-m) for the alpha-Fe2O3 nanoparticles formed via the sol and sol-gel processes are 2 < D-m < 3 and 3 < D-m < 4, respectively.
