    摘要:

    用葡萄糖作為還原劑制備銀包銅粉。在還原法鍍銀過程中，主鹽溶液以不同的工藝添加可得到不同微觀形貌和表觀顏色的銀包銅粉，用掃描電鏡、能譜儀對銀包銅粉進(jìn)行表征，并用滴定法計算不同添加工藝制備的銀包銅粉的含銀量，確定了較優(yōu)的主鹽添加工藝；同時，通過在施鍍過程中階段性取粉觀察，對銀包銅粉鍍層的沉積過程進(jìn)行了分析。

    Abstract:

    The silver-coated copper powders were prepared by a reduction method, using glucose as the reductant. The different adding processes of silver-ammonia solution varied the micro-morphology and appearance color of the powders. The coated powders were characterized by SEM and EDS. The silver contents of different adding processes were calculated by titration. Thus the optimal adding process was determined. Meanwhile, the silver coating deposit process was analyzed by observation of the powders taken out from the solution at different stages during silver plating.
