摘要
Dendrite and platelet-like alpha-Fe2O3 microcrystals were synthesized by the oxidation reaction of K4Fe(CN)(6) and NaClO3 through a simple hydrothermal method. The structures and morphologies of the as-prepared samples were characterized in detail by X-ray diffraction (XRD), transmission electron microscopy (TEM) and scanning electron microscopy (SEM). The experiment results show that NaOH played an important role in controlling the morphology of the final products. The possible mechanism was discussed to elucidate the formation of different morphologies of the alpha-Fe2O3 microstructures. Besides, the magnetic property of the dendrite alpha-Fe2O3 microstructure was characterized by a vibrating sample magnetometer (VSM). (C) 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
