ABSTRACT:

The liquidus temperatures in the CsCl–PbCl2–PbO ternary system with lead oxide addition reaching 0.0 to 20.0 mol. % were determined using methods of thermal analysis of cooling curves and differential scanning calorimetry. The temperature dependence of the PbO dissolution in the CsCl (18.3 mol. %)–PbCl2 (81.7 mol. %) and CsCl (71.3 mol. %)–PbCl2 (28.7 mol. %) chloride eutectics was determined and thermodynamic parameters of dissolution were calculated. The mechanism of chemical interaction between lead oxide(II) and chloride melts was testified.
