| 摘 要： | 介绍了一种制备无水高纯氟化镝的新方法。在氟化炉内的镍制料盘中直接完成了Dy2O3和无水氟化氢气体的氟化反应，然后将钙热还原DyF3制得的粗镝进行熔盐萃取提纯处理，用此式敢可使工业规模化生产的镝金属中的氧，氟含量均小于0.02%，使金属镝的纯度达99.9%以上。

Preparation of High Purity Dysprosium Metal Using Anhydrofluorination |
| |
| Abstract: | A new method used to prepare the high purity anhydrous dysprosium fluoride was proposed. Direct reaction of Dy 2O 3 with anhydrous HF was carried out in a nickel boat inside a fluorinated furnace. The rough dysprosium was made by calcium thermal reduction of anhydrous DyF 3 and then was purified by fused salt extraction. This method can make the amount of O and F smaller than 0.02% and the purity of dysprosium metal reach above 99.9% in industrial process of producing dysprosium metal. |
