Abstract: | A thermodynamic analysis of the phase equilibria in the Pb-Sn-Sb ternary system was conducted. A regular solution approximation
based on a two-sublattice model was adopted to describe the Gibbs energy of formation of the individual phases in the binary
and ternary systems. In the case of some component binary systems, the effect of pressure also was considered. Experimental
data obtained by differential thermal analysis (DTA) and electron probe microanalysis (EPMA) in the present study, along with
literature data on phase boundaries and thermochemical properties, form the basis for the evaluated thermodynamic parameters
used in the calculation. Calculated and experimental phase boundaries agree fairly well.
