摘 要：<正>The preparation of nanostructured tungstenpowders has been studied by using the characteristics of high-er temperature, higher chemical reactivity and quenchingtechnology of hydrogen plasma,in which WO3 solid particlesserved as raw materials. The reduction mechanism of WO3 athigh temperature has been also discussed. The composition,particle size distribution and morphology of nanostructuredtungsten powders have been measured by X-ray diffraction,small angle X-ray scatter and TEM. Tungsten powders ofmean particle size of 40 nanometer,and specific surface areaof 3×104m2/kg have been prepared. The shape of nanostruc-tuted tungsten powders is sphere.
