Chemical analysis methods of non-rare earth impurities in rare earth metals and their oxides—Part 13:Determination of molybdenum and tungsten content


Standard in brief
Scope of Application:  
本文件描述了稀土金属中钼、钨含量的测定方法。
本文件适用于稀土金属中钼、钨含量的测定。电感耦合等离子体发射光谱法(方法1)测定范围(质量分数):0.0050%~0.50%。电感耦合等离子体质谱法(方法2)测定范围(质量分数):0.0001%~0.10%。当测定范围出现重叠时,以方法1作为仲裁方法。
