Novel Fe(3)O(4) octahedrons and Fe microtubes were successfully prepared in different alkaline concentration solutions by the reduction of hematite (alpha-Fe(2)O(3)) with hydrazine hydrate. The as-prepared powders were characterized in detail by conventional techniques such as X-ray diffraction and field emission scanning electron microscopy. The role of alkaline concentration during the reaction process is discussed in detail. Compared to the reaction in a water system, the reaction in ethanol required less sodium hydroxide and smaller particles were obtained. In addition, the magnetic properties of the samples were characterized using a vibrating sample magnetometer.
