采用化学液相均相沉淀法制备出纳米Ｍｎ２Ｏ３材料，并用Ｘ射线衍射（ＸＲＤ）、透射电镜（ＴＥＭ）和高分辨电镜（ＨＲＥＭ）对其微结构特点进行了研究．首次在Ｍｎ２Ｏ３材料中观察到了分形凝聚现象．
Nanometer Mn2O3 nanocomposites were prepared by chemical liquid phase precipitation. The microstructures of nanometer Mn2O3 were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM) and high resolution electron microscopy (HREM). Fractal cohesion was observed for the first time in Mn2O3 materials.
