摘要
研究了直接还原-真空蒸馏法和中间合金-真空蒸馏法制备高纯金属铽的工艺,对原辅材料纯度、工艺路线和蒸馏温度对产品纯度的影响以及真空蒸馏对杂质的去除效果进行了讨论,并采用直接还原-真空蒸馏工艺制得了国内目前质量最好的金属铽。
The intermediate alloy vacuum distillation and direct reduction-vacuum distillation method for preparing high purified Tb metal have been studied, The influence of raw material purity and preparation route, distillation temperature on product purity and the effect of impurity removal by vacuum distillation were discussed, The best high purified Tb metal in China was prepared by direct reduction-vacuum distillation method
