摘　　要：以CuSO4溶液为主要原料，采用电沉积法快速制备高纯超细铜粉。利用X射线衍射仪（XRD）和扫描电镜（SEM）表征铜粉的粒度和微观形貌。结果表明，阴极材质和超声波对铜粉的微观形貌和粒度均具有重要影响，超声波可有效降低铜粉的平均粒径，铝材质阴极形成粒度范围0．01—0．5um的球形铜粉，铁材质阴极形成粒度范围为0．1～1．5um的不规则球形和方形铜粉。The high-purity and ultra-fine copper powder was prepared quickly by using electro- deposition method with CuSO4 solution as the main material. The particle size and morphology of the ultra-fine copper powder were investigated by XRD and SEM. The results show that the cathode materials have important effects on micro morphologies and particle size range of ultra-fine copper powder and the supersonic wave can reduce the average particle size of copper powder effectively. Using pure A1 as cathode, the morphology of copper powder is spherical and the particle size range is 0.01 --0.5um. The morphology of copper powder is irregular spherical and square, the particle size range is 0.1- 1.5 um with Fe as cathode.
