稀土镁合金试样的处理,一般采用在铂器皿中氢氟酸溶解。我们试验了不用铂器皿的分析方法,可在同一试液中连测几个元素。方法简便易于掌握,缩短了分析时间,再现性良好,适合一般试验室快速分析。概要:稀土中间合金主要成份有硅、稀土、镁、 Rare earth magnesium alloy sample processing, the general use of hydrofluoric acid dissolved in platinum vessels. We experimented with an analytical method that does not use platinumware and can test several elements in the same test solution. The method is simple and easy to grasp, shortens the analysis time, has good reproducibility and is suitable for general laboratory analysis. Summary: The main components of rare earth master alloys are silicon, rare earth, magnesium,
