微米级球形铜粉的制备

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).%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.
