摘　　要：研究了锡铅银等低熔点合金中杂质氧的测定方法。针对这些金属高温下易挥发、分解的特点 ,选择适宜的加热温度 ,使用铜和石墨粉作为浴料 ,选择标准坩埚 ,以电流 92 0A加热进行试验。对氧的质量分数为 0 .0 1 7%的试样 ,分析精密度为 5 .9%,加标回收率为 91 %～ 1 0 8%。The determination of oxygen in alloy of tin-lead-silver with lower melting point was studied. Suitable conditions for the determination of oxygen in the alloy were optimized. The method was used to determine oxygen in real samples with satisfactory results. The relative standard deviation was 5.9%, and recovery was in the range of 91%～108%.
