对固态电解做为提纯技术制备高纯钆的实用情况,做了描述和评价。使用超高真空和两个周期操作,钆中氧的含量降低两个数量级,其他杂质数量也有很大降低。做出的钆比以前报导的有更高的纯度和电阻比。另外在纯的样品中常常产出大的单晶。 The solid state electrolysis as a purification technology for the preparation of high-purity gadolinium practical situation, made a description and evaluation. With ultra-high vacuum and two cycle operation, the oxygen content in gadolinium is reduced by two orders of magnitude and the amount of other impurities is greatly reduced. Gadolinium made higher purity and resistance than previously reported. In addition, large single crystals are often produced in pure samples.
