关于钆电解精炼的 LiCl—LiF—GdF_3、LiF—GdF_3和 LiF—BaF_2—GdF_3熔盐体系评价。发现在最终产物中金属杂质的总数少于50(重量)PPm,每个间隙杂质元素 H、C、N、O 和 F 少于100(重量)PPm。虽然 LiF—GdF_3这种电解质及其沉积物是在空气中被处理,但就氧而论此种电解质产生了高纯钆金属。金相和化学分析证明:用电子束熔炼方法从金属中除去氟化物杂质,取得了最好的结果。 Evaluation of LiCl-LiF-GdF_3, LiF-GdF_3 and LiF-BaF_2-GdF_3 Molten Salt Systems for Gadolinium Electrolysis Refining. It was found that the total amount of metal impurities in the final product was less than 50 wt.% PPm and the amount of H, C, N, O and F in each gap was less than 100 wt.% PPm. Although LiF-GdF_3 this electrolyte and its deposits are treated in the air, this electrolyte produces high purity gadolinium metal in terms of oxygen. Metallographic and chemical analyzes have demonstrated that the best results have been achieved with electron beam melting to remove fluoride impurities from the metal.
