Nanometer level α-Fe2O3 is a sort of important nanometer material, which can be used comprehensive in the field of catalysis, ultraviolet radiation absorption material, functional ceramics and so on. This article uses the method of microwave radiation combined with high temperature sintering to prepare dispersive and symmetrical α-Fe2O3 nanometer grains for the first time, and this method not only may reduce the reactive cycle, but also may enhance the concentration of reactive initial solution of FeCl3. At the same time, in the process of experiment we found that if we put different crystal promotion agents in reaction solution at different calcining heat and calcining time, we can obtain round, cubic or rod-like α-Fe2O3 nanometer grains separately.
