| 中文摘要 | Stepwise chlorination-chemical vapor transport (SC-CVT) reaction has been investigated for the rare earth oxide mixtures Gd2O3Tb4O7, Tb4O7-Dy2O3 and Dy2O3-Ho2O3 mediated by vapor complexes LnAl(n)Cl(3n+3) (where Ln=rare earth elements). The results show selective deposition of lighter elements at higher temperatures. The separation factors are 5.84 for Gd/Tb, 3.72 for Tb/Dy and 3.13 for Ho/Dy when using CO as the CVT carrier gas. A combination of enhanced separation factor with reduced total transport yield is also observed for the Tb4O7-Dy2O3 system when using argon as the CVT carrier gas. (C) 2002 Elsevier Science B.V.
