摘　　要：为探究影响超细铜粉分散性的影响因素,以超细铜粉的粒径为指标,应用正交设计法,探究粉体制备工艺中常用的4种处理方式对超细铜粉粒径的影响。结果表明,当采用5%PVP,3%NaH_2PO_2,20%乙醇混合溶液,80℃水浴条件下,1 k W超声处理1 h后,可得到分散性较好,平均粒径为0.43μm,基本为球形的超细铜粉。In order to explore factors influencing the dispersibility of ultrafine copper powder,by taking particle diameter of ultrafine copper powder as an index,orthogonal experimental design method was applied to investigate four treatment methods that are commonly used in the powder preparation process. The results showed that in mixed solution with 5% PVP,3% NaH_2PO_2 and 20% ethanol after 1000 W ultrasonic treatment for 1 h under 80°C water bath condition,ultrafine copper powder were obtained which has better dispersibility,an average particle diameter of 0.43 μm,and substantially spherical shape.
