The excess enthalpies of liquid alloys in the ternary Ga-Pb-Te system were determined at 1173 K in a heat-flow calorimeter for the sections GayPb1-yTe with y = 0.2, 0.4. 0.5, 0.6 and 0.8 and for the section Ga0.5Pb0.5-Te at 1073 K. The enthalpy surface in the ternary system is characterized by a line of minima from the composition Ga2Te3 to the composition PbTe in the limiting binaries. The excess enthalpies in the binary systems were fitted with the association or regular solution model using the program of H.-L. Lukas. For an analytical description of the ternary system, the association model was used with additional ternary interaction parameters, (C) 1999 Published by Elsevier Science B.V. All rights reserved.
