摘要
Based on the thermodynamically self-consistent analysis and optimization of three sub-binary systems of the ternary system PrCl_3-CaCl_2-MgCl_2,the thermodynamics of this ternary system has been studied.Using Hillert model and taking MgCl_2 as an asymmetric component,the PrCl_3-CaCl_2-MgCl_2 phase diagram has been calculated.The agreement between calculated and measured compositions and temperatures at deflecting points on liquidus is good.The system is a simple eutectic one with a eutectic point at 26.0mol% PrCl_3, 41.5mol% CaCl_2,32.5mol% MgCl_2;560℃(calculated)and 26.0mol% PrCl_3,39.4mol% CaCl_2,34.6mol% MgCl_2;546℃(measured),respectively.
