摘要
为了保证金属铯能够达到铯束管的要求,根据金属铯中的杂质在同一温度下的饱和蒸气压比金属铯低的特性,采用真空多级蒸馏的提纯方法,研制了一套多级真空蒸馏装置。该装置具有结构简单,蒸馏过程直观,对真空泵组污染小等特点。
In order to ensure cesium metal could meet the need of the Cesium Beam Tube （CBT）, developed a multilevel vacuum distillation device .Based on the speciality the vapor tension of metal cesium is much higher than other impurity at the same temperature, This device has many characteristic such as simple structure,intuitionistic distillation process, and less pollution to the vacuum pumps.
