摘　　要：采用自行设计的超声波固液反应球磨机在蒸馏水中对铜粉进行球磨,成功地制备了纳米级氧化铜粉末,其球磨产物的化学成分、粒度和微观结构分别通过X射线衍射和透射电镜(TEM)进行表征。实验结果表明在超声波作用下的固液反应球磨铜粉可以生成平均粒径在20nm左右的纳米氧化铜粉末。与没有施加超声波作用的水溶液球磨相比,超声波能对固液化学反应进行干预从而使得纳米氧化铜生成速度提高2倍以上,但对其粒度的影响不明显。Cu powders were milled in the distilled water by solid-liquid reaction ball mill equipment under ultrasonic waves,which was designed by ourselves.CuO nanopowders could be attained because of the strike-peeling processing of ball milling.The compositions,particle size and the microstructures of the as-milled products were characterized by X-ray diffraction and TEM.The experimental results showed that under ultrasonic waves processing CuO nanopowders with average size about 20 nm could be attained between Cu and water solution reaction.For comparison,Cu powders also were milled in the distilled water without ultrasonic waves.Ultrasonic waves have obviously effect on the reaction route,which are beneficial to attain CuO nanopowders,and the reaction velocity of milling under ultrasonic waves processing can be more two times than that without ultrasonic waves,but the size of products is hardly changed under milling with ultrasonic waves and without ultrasonic waves,respectively.
