In present work.the ultrafine manganese particles were prepared by gas evaporation method.The structure,size distribution,growth morphology and surface oxidation for the particles were investi- gated by using X-ray diffraction and electron microscopy.The results indicated that three types of the particles,with the structure of α-Mn,β-Mn and one unknown,respectively existed in the man- ganese particles.The growth morphology of the particles depended on the size and intrinsic structure.When exposed to air,the particles were slightly oxidized only in the surface layer and sta- ble in air.
