【摘要】用SETARAM量热计测量了873K时富PbCl₂区域PbCl₂-NaCl-Bacl₂三元熔盐的混合焓。结果表明,PbCl₂活度相等的液态亚二元系PbCl₂-NaCl和PbCl₂-BaCl₂之间的摩尔混合焓近似地等于零,即近似地符合偏理想溶液模型。更多还原

【Abstract】 The enthalpies of mixing for the PbCl₂-NaCl-BaCl₂ ternary molten salt mix-tures have been measured along four iso-α_PbCl₂ lines by using a SETARAM calorimeter at873 K. The results show that the molar enthalpy of mixing between iso-α（PbCl₂） liquid binarysubsystems PbCl₂-NaCl and PbCl₂-BaCl₂ is near zero, i. e., approximately fitting the partialideal solution model.更多还原
