摘　　要：讨论了化学还原--机械球磨制备片状银粉的生产工艺。通过正交试验法安排试验,分析了前驱体银粉制备工艺及球磨工艺对最终片银粒度分布等性能的影响,得出的较优工艺参数组合是:硝酸银初始浓度为60 g/L,水合联氨初始浓度为80 g/L,分散剂用量为硝酸银质量的0.4%,结果表明,该工艺参数组合制备的片银粒度分布的D50在3μm^4μm。Production technology of flake silver powder made by chemical reduction and mechanical was studied. Applying the table of orthogonal arrays testing method, the influence of process of silver powder feed making and ball milling on the particle size distribution of flake silver powder were discussed. The optimal conditions are that the concentration of AgNO3 is 60g/L, the concentration of N2H4 · H2O is 80 g/L, dispersant/AgNO3 （weight ratio） is 0.4%. and the results show that D50 of flake silver powder particle size distribution is 3 μm - 4 μm.
