Abstract
Purification of rare earth metals with high vapor pressure below melting point (Sm, Eu, Tm, Yb) have been carried out by high and ultra-high vacuum sublimation and distillation, using direct sublimation, sublimation with a porous solid W filter and novel promising liquid metal through distillation (LMTD). Using the last two methods, high purity RE metals with RRR of about 300 were obtained. Aspects of experimental setup and conditions and its influence on behavior and redistribution of impurities are analysed and future perspective of methods are discussed.
