纳米Mn_2O_3的制备及其分形凝聚

Preparation and Fractal Aggregation of NanometerSized Mn2O3

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sized manganic oxide(Mn2O3) is prepared for the first time by a chemical liquid homogeneous precipitation(CLHP) method. Its microstructure is studied with Xray diffraction(XRD), transmission electron microscope(TEM) and high resolution electron microscope(HREM). From transmission electron micrographs, phenomena have been observed of fractal aggregation in nanometersized Mn2O3.
