| 中文摘要: |
| 在新生成的铜微粉表面化学镀银,用扫描电镜、X射线衍射仪、动态光散射粒径测试仪和热重仪对粉体进行表征和性能测试,分析了粉体导电性、抗氧化性及粒径大小和分布的影响因素。结果表明:在乙二醇介质中采用液相还原法,通过葡萄糖预还原,用甲醛进行二次还原,控制银与铜物质的量之比为2:1,可得到抗氧化性、导电性良好的银包铜微粉。 |
| 英文摘要: |
| The surface of copper powers was plated with silver. The silver-coated copper power was characterized and its performances were tested by XRD,DLS and TG.The influence factors of conductivity, antioxidativity and its particle size were analyzed. The results show that silver-coated copper powders are prepared by liquid chemical reduction methed, which glucose as prereductant and formaldehyde as reductant in ethylene glycol system. The mole ratio of copper and silver is 2:1. Silver-coated copper powders exhibit excellent conductivity and antioxidativity. |
