Dendrite and platelet‐like α‐Fe 2 O 3 microcrystals were synthesized by the oxidation reaction of K 4 Fe(CN) 6 and NaClO 3 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 α‐Fe 2 O 3 microstructures. Besides, the magnetic property of the dendrite α‐Fe 2 O 3 microstructure was characterized by a vibrating sample magnetometer (VSM). (© 2010 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
