Abstract 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–AlCl3, 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.
