| 中文摘要: |
| 采用熔融冷却法制备了Na-Ca系无铅低熔玻璃粉，利用DSC对所得玻璃粉进行表征。通过改变玻璃粉含量、粒径，研究其对银浆性能的影响。结果表明，玻璃粉软化温度为546℃；随着玻璃粉含量增加，银膜方阻先减小后增大，当玻璃粉含量为4%时银膜方阻最小为17 mΩ/□；随着玻璃粉粒径增加，银膜方阻先减小后增大，当玻璃粉粒径为2.47 μm时，银膜方阻最小为14 mΩ/□。 |

| A lead-free low-melting glass frit based on Na-Ca system was prepared by melt-quenching method. Na-Ca glass frit was characterized by differential scanning calorimetry (DSC). The effects of changing content and particle size of the glass frit on properties of silver paste were investigated. The results showed that the glass softening temperature is around 546℃. The silver film square resistance decrease first and then increase as the content of glass frit increases. The silver film square resistance reaches the minimum 17 mΩ/□ at the glass frit content of 4％. The silver film square resistance decrease first and then increase as the particle size of glass frit increases. The silver film square resistance reaches the minimum 14 mΩ/□ at the glass frit particle size of 2.47 μm. |
