摘　　要：采用电阻加热蒸发冷凝法,在N2保护气氛下,制得铜纳米粉末。通过X射线衍射检验确定制成的铜纳米粒子具有fcc相,并且纯度较高;用透射电镜对粒子的形貌和粒径进行了表征分析,结果显示粒径在20 nm左右,分散性好。Protected by N2, copper rumoparticles were produced using resistance heat evaporative cooling method. The structure of copper nanoparticles were measured by XRD, the dimension was surveyed by TEM. The result showed that the copper nanoparticles consist of fcc phase, and the average size is about 20 nm.
