摘　　要：采用通常的化学液相均相沉淀法首次制备出了纳米Mn2O3材料．X射线衍射（XRD）和透射电镜（TEM）观察表明纳米Mn2O3的颗粒在9-50nm；9纳米的Mn2O3顺磁共振（ESR）谱图观察到六线峰精细结构。Nanometer-sized manganic oxide(Mn2O3) has been prepared for the first time by a chemical liquid homogeneous precipitation (CLHP) method. Transmission electron micrographs and X-ray powder diffraction patterns show that the average particle sizes are in the range of 9-50urn. From the Electron Spin Resonance(ESR) patterns of 9nm manganic oxide particle, we can observe hyperfine structure:Six absorption peaks of ESR signal.
