Abstract: The nanocrystalline pure copper powders are prepared by using KBH4,CuSO4,KOH,EDTA and PVP by reduction in acqueous solution. The impurity such as Cu2O can be removed by adjusting the content of reactant. The effect of dispersing agent PVP on the purities of copper powders is studied. The result shows that dispersing agent PVP is benefit to the disperse of powders.

Key words: nanocrystalline copper powder； reduction in acqueous solution； dispersing agent；
