| 摘 要： | 银钯浆料具有较好焊接性与抗银迁移能力及可调的烧结温度，使得银钯复合粉在厚膜微电子浆料中占有重要的地位。采用水合肼作为还原剂，通过表面活性剂种类的选择、加入方式的改变及加入量的控制，制备了不同形貌的Ag-10Pd复合粉。结果表明，聚乙烯吡咯烷酮对制备单分散的多面体银钯复合粉有较好的作用，而明胶的加入可以获得较好的球形复合粉，对其加入方式与加入量进行调控，可以选择性制备不同粒径与形态的Ag-10Pd复合粉。

| Abstract: | Silver-palladium paste has a very important position in the fields of thick film microelectronic pastes due to its good weldability, resistance to silver migration and adjustable sintering temperature. In this paper, by using hydrazine hydrate as a reducing agent, Ag-10Pd composited powder of different shapes was prepared through the selection of surfactants, the variation of the addition methods and the control of the amount of surfactants. The experimental results showed that polyvinylpyrrolidone had a good effect on synthesizing monodisperse polyhedral silver-palladium powder, while by the addition of gelatin, the spherical composited powder could be obtained. The particle sizes and shapes of Ag-10Pd powder could also be regulated and controlled by different addition methods and the addition amount of gelatin, respectively. |
