摘　　要：本文就采用常压歧化法制得的微细铜粉的形貌、颗粒线尺寸、粒度分布、松装密度、摇实密度、化学成分、抗氧化性能 ,及其在烧结过程中的行为等物理与化学性能进行了测定与探讨。结果表明 ,在优化条件下所得微细铜粉性能完全符合电子浆料用铜粉的要求。In this paper were measured and discussed the physical and chemical characteristics,such as morphology,particle size and its range,loose and packing density,impurity content,resistance to oxidation as well as behavior in sintering process of fine copper powder prepared by disproportionation under normal pressure.The experimental results show that the fine copper powder prepared under optimum condition meets well the requirement for production of conductive ink.
