Phase Diagram Determination Of The Dyspromium And Potasium Chloride Melts

摘要

The intermediate compounds, K_3DyCl_6, K_2DyCl_5 and KDy_2Cl_7, in the DyCl_3-KCl system, are confirmed by X-ray powder diffraction method. With CALPHAD technology the phase diagram of the DyCl_3-KCl system is re-optimized and calculated using ChemSage software. A set of thermodynamic functions has been optimized based on an interactive computer-assisted analysis. The calculated phase diagram and optimized thermodynamic parameters are thermodynamically self-consistent.
