Abstract

Novel Fe3O4 octahedrons and Fe microtubes were successfully prepared in different alkaline concentration solutions by the reduction of hematite (α-Fe2O3) 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.
