| 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 relatedto 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 DTA.Attempts were also made to explore the rule governing thealteration in the phase diagram containing rare earth chloride,formation of compoundand its stability by means of polarization and counter-polarization.

| Abstract: | 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 DTA.Attempts 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. |
