摘要：

Mutual separations between mixed lanthanoid chlorides, LnCl3 (Ln=Pr and Nd), were performed using a chemical-vapor transporting method via gaseous complexes with a series of alkaline metal chlorides (ACl). The resulting separation factor depended slightly on the alkaline metals, indicating a tendency for the factor to increase with the atomic number; good separation characteristics were observed for gaseous complexes with KCl and RbCl. For complexes in ternary systems, LnCl3-ACl-AlC13, the codeposition of ACl with LnCl3, which took place in the binary system, LnCl3-ACl, was depressed and LnCl3 was obtained in a form free from the used complex formers.
