高纯金属镝的制备工艺研究与工业实践
Study and Commercial Operation of High-purity Dy Metal
【摘要】 对高纯金属镝的制备工艺进行了研究 ,并用此工艺进行了工业实践。表明 :采用氟化氢氟化-制备中间合金 -低温蒸馏 -高温蒸馏的工艺流程 ,是工业生产高纯金属镝较为适宜的方法
【Abstract】 Preparation process and commercial operation of high-purity dysprosium metal is studied.The results show that it is applicable to adopt the process flowsheet of HF gas fluoridization-preparation of intermediate alloy-vacuum distillation-low temperature-high temperature vaccum distillation for commercial production of high-purity Dy.
