| 摘 要： | Four different hematite (α-Fe2O3) nanopowders with various morphologies have been synthesized in the presence of surfactant (HPC) via hydrothermal route at 180 ℃, using four kinds of iron salts, Fe2(SO4)3, FeC2O4, FeSO4 and (NH4)3Fe(C2O4)3, as precursor materials. The products were characterized by means of X-ray diffraction (XRD), transmission electron micrograph (TEM), Fourier transform infrared spectroscopy (FTIR) and magnetization measurements. The hysteresis measurements show that the products exhibit weak ferromagnetic property at room temperature. It is concluded that the different precursor materials and the presence of the surfactant are important factors that exert significant effects on the morphologies and magnetic properties of the products.
