摘　　要：钙、镁、锰是稀土硅铁及镁硅铁合金产品中重要的指标,采用全谱直读等离子光谱法测定稀土硅铁及镁硅铁合金中的钙、镁、锰量,无须基底匹配,采用工作曲线法对多个元素同时测定,结果稳定可靠。相对标准偏差(RSD)小于2.63%,与其他分析方法相对照,测定结果较为吻合。测定范围:Ca:0.50%～6.00%,Mg:0.20%～11.00%,Mn:0.20%～4.00%。Determination of Ca, Mg and Mn in RE - Mg - Si -- Fe alloy was carried out by ICP - AES technique, multiple elements were determined by the working curves without matrix matching in this experiment, and the results were reliable. RSD was less then 2.63 and agreement with those by other methods. The determination range of Ca,Mg and Mn is 0.50 - 6.00%, 0.20 - 11.00% and 0.20 - 4.00% ,respectively.
