| 摘 要： | 分析了熔炼方法对银熔体材料纯度、微观组织和电阻率的影响。对比普通熔炼方法,二次熔炼方法得到的银材料由II号银(99.95%)变成I号银(99.99%);氧含量降低至少85%以上,纯银熔体材料电阻率降低约1.54%。杂质元素主要集中在晶界处,纯银熔体材料电阻率随杂质含量的减少而减小,二次熔炼方法可有效提高纯银熔体材料质量、稳定其电学性能。

| Abstract: | The influence of smelting method on purity of silver melt material, microstructure and resistivity of pure silver alloy was investigated. Compared to ordinary smelting method, research and development of secondary smelting method to get pure silver materials by Ag-II (99.95%) into Ag-I (99.99%). The oxygen content was decreased at least 85%, and the resistivity of pure silver solute was reduced about 1.54%. Impurity elements mainly concentrated in the grain boundary, the resistivity of silver melt material decreases with the decrease of impurity content, secondary smelting method can effectively improve the quality of pure silver melt material, stable electrical properties. |
