Abstract: The formation process of pseudo-spherical α-Fe2O3 particles obtained through the hydrolysis of 0.01 mol·L-1 FeCl3 solution was studied by means of TEM and XRD. The results show that the growth of α-Fe2O3 nuclies is through the diffusion mechanism. Although the presence of CTAB in the FeCl3 solution has no effect on the growth process of pseudo-spheric α-Fe2O3 particles, more uniform particles are obtained, and the particles are self-assembled to form two-dimensional ordered structure due to the effect of CTAB. The optical character of these α-Fe2O3 particles was investigated, and the band-gap of which is about 2.49 eV.
