用SETARAM量热计测量了873K时富PbCl_2区域PbCl_2-NaCl-Bacl_2三元熔盐的混合焓。结果表明,PbCl_2活度相等的液态亚二元系PbCl_2-NaCl和PbCl_2-BaCl_2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。
The enthalpies of mixing for the PbCl_2-NaCl-BaCl_2 ternary molten salt mix-tures have been measured along four iso-α_(PbCl_2) lines by using a SETARAM calorimeter at873 K. The results show that the molar enthalpy of mixing between iso-α(PbCl_2) liquid binarysubsystems PbCl_2-NaCl and PbCl_2-BaCl_2 is near zero, i. e., approximately fitting the partialideal solution model.
