摘要
The pseudobinary systems NaCl—LnCl3 (Ln=Tm, Yb, Lu) were investigated by DTA and X-ray diffraction. Two types of ternary chlorides exist: congruently melting compounds Na3LnCl6 with the cryolite-structure, incongruently melting compounds NaLnCl4 with the NaErCl4-Ln (Ln=Tm) or the NaLnCl4-structure (Ln=Yb, Lu). All these structure types contain [LnCl6]-octahedra.
