【Abstract】 α-Fe₂O₃ nanoparticles were successfully prepared by a sonochemical method in FeCl₃-NH₃ complex solution.The obtained sample was examined and investigated by XRD,TEM,FT-IR,FT-Raman and XPS techniques.The results showed that the spherical,well-dispersed α-Fe₂O₃ nanoparticles were obtained with the average size of 15nm.The possible formation mechanism of α-Fe₂O₃ nanoparticles were also discussed,which indicated that this for the preparation of the nanoparticles method can be used for α-Fe₂O₃ preparation with some practical and universal significance.更多还原
