| Abstract: | In this paper, the phase diagram of the DyCl_3-NaCl system is optimized and calculated with CALPHAD (calculation of phase diagram) technology. A set of thermodynamic functions of compounds Na_3DyCl_6, NaDyCl_4, and NaDy_2Cl_7 have been optimized and calculated based on an interactive computer-assisted analysis. The optimized thermodynamic parameters, calculated phase diagram and experimental phase diagram are thermodynamically self-consistent. |
