Abstract: Well-dispersed α-Fe2O3 parallelepiped nanocrystals have been successfully prepared via a hydrothermal synthetic route. The shapes and structures of the products were characterized by using powder X-ray diffraction and scanning electron microscopy. The results showed that the α-Fe2O3 samples have a parallelepiped shape with an average parallel side of 80–90nm and thickness of 60–70nm. The parallelepiped nanocrystals exhibited a ferromagnetic behavior with the coercive force, saturation magnetization, and remanent magnetization of 920Oe, 0.44emu/g, and 0.17emu/g, respectively. The crystal growth process was discussed on the basis of time-dependent experimental results. [Copyright &y& Elsevier]
