中文摘要:

超级严肃地被采用为铜粉末的准备提高电解反应。铜粉末的形态学,微观结构和尺寸被扫描电子显微镜学, X 光检查 diffractometry 和激光粒子分析描绘。结果显示在超级严肃地下面的电解的铜粉末的当前的效率在正常严肃状况下面与那相比增加了超过 20% 。在超级严肃地下面的房间电压也低得多。铜粉末的尺寸随严肃系数(G) 的增加减少了。当前的效率的增加能被贡献电极 / 电解质接口的骚乱和在超级严肃的 Cu2+ 的提高的集体转移域。同时,巨大的严肃加速将在电解过程期间从电极表面支持铜粉末的分开,它能阻止铜粉末的生长。

英文摘要:

Super gravity field was employed to enhance electrolytic reaction for the preparation of copper powders.The morphology, microstructure and size of copper powders were characterized by scanning electron microscopy,X-ray diffractometry and laser particle analysis.The results indicated that current efficiencies of electrolytic copper powders under super gravity field increased by more than 20% compared with that under normal gravity condition.Cell voltage under super gravity field was also much lower.The size of copper powders decreased with the increase of gravity coefficient(G).The increase of current efficiency can be contributed to the disturbance of electrode/electrolyte interface and enhanced mass transfer of Cu^2+ in super gravity field.Meanwhile,the huge gravity acceleration would promote the detachment of copper powders from electrode surface during electrolytic process,which can prevent the growth of copper powders.
