| Abstract: | Based on thermodynamics and kinetics analysis for preparation of metallic ytterbium by the process of lanthanum thermal reduction, preliminary process parameters were determined. By using high-purity ytterbium as raw material, self-produced metallic lanthanum as reducing agent, high vacuum furnace with tantalum sheet as reaction device, ytterbium(99.985% purity) was obtained after several times of distillation at 1 200 ℃. The predominant influencing factors for metal purity were also analyzed. |
