主　　题：PrCl_3 PrCl-3-SrC1_2-CaCl_2 phase diagram rule of pihase diagram 

摘      要：Five fields corresponding to the primary crystallization of PrCl_3,Sr_3PrCl_9,α(SrCl_2, CaCl_2),α_1(CaCl_2,SrCl_2)and α_2(SrCl_2,CaCl_2)respectively,six univariant lines related to the secondary crystallization,one ternary eutectic(48.0 wt-％ PrCl_3,23.5 wt-％ SrCl_2; 590℃)and ternary peritectic point(45.5 wt-％ PrCl_3,24.5 wt-％ SrCl_2;614℃) were determined by *** were also made to explore the rule governing the alteration in the phase diagram containing rare earth chloride,formation of compound and its stability by means of polarization and counter-polarization.
