| 中文摘要: |
| 针对超细银粉制备工艺中易于团聚等现象，对离子液体介质中银粉制备工艺进行了研究。将离子液体加入到硝酸银溶液中，在不同工艺条件下进行还原，并对所制备的银粉采用X射线衍射、扫描电镜进行结构表征，利用激光粒度仪分析了所制备银粉的粒径及粒度分布。结果表明离子液体的加入量对银粉的形貌、结晶状态以及粒度分布有较大影响，在100 mL的AgNO3(0.05 mol/L)，1 g PVP，10 mL离子液体，油浴温度120℃条件下制得的银粉性能最优。 |
| 英文摘要: |
| In order to protect the ultrafine silver powder from the agglomeration, the preparation process of silver powder in ionic liquid was studied. The ionic liquid was mixed with silver nitrate solution and reduced under different conditions. The structure, surface morphology, particle size and size distribution of the silver samples were studied by XRD, SEM and laser particle size analyzer. The results showed that adding quantity of ionic liquids has a great influence on the morphology, crystallization and particle size distribution. The best performance of silver powder can be obtained under the process conditions: 100 mL AgNO3 (0.05 mol/L), 1 g PVP, 10 mL ionic liquids, and reaction at 120℃. |
