中文摘要:

      以抗坏血酸为还原剂，一定条件下还原硫酸铜氨溶液可以得到微米级球形铜粉。样品经X-射线衍射和扫描电子显微镜测定，并探讨了反应机理。

英文摘要:

      Spherical micrometer-size copper particles were synthesized by chemical reduction of cuprammonia sulfate solution with ascorbic acid as reducing agent. The sample was perfectly sphere and it was characterized by X-ray diffraction and scanning electron microscopy (SEM).
