摘　　要：以硫酸铜为原料,水合肼为还原剂,在70℃左右,pH为11时反应合成了纳米铜粉;采用X射线衍射仪对铜粉进行了表征;讨论了制备条件对纳米铜粉的影响。In this paper ,Nano-copper powders were prepared by using CuSO_4·5H_2O as precursor and N_2H_4·H_2O as reducing reagentat at 70℃ with pH=11. The composition and size of Nano-copper powders were analyzed by XRD technique. The effect of preparation condition on the stability of Nano-copper powders in the distilled water and solution of benzotriazole were studied.
