Abstract
The thermodynamic modelling of the La-Pb binary system was carried out with the help of CALPHAD (CALculation of PHAse Diagram) method. La5Pb3, La4Pb3, La5Pb4, αLa3Pb4, βLa3Pb4, LaPb2, LaPb3 have been treated as stoichiometric compounds while a solution model has been used for the description of the liquid, BCC and FCC phases. The calculations based on the thermodynamic modeling are in good agreement with the phase diagram data and experimental thermodynamic values.
