The excess enthalpies of liquid alloys in the ternary system Ga-In-Te were determined at 1173 K in a heat flow calorimeter for five sections Ga y In 1 - y Te with y=0.2, 0.4, 0.5, 0.6 and 0.8 and, in addition, for the section Ga 0 . 5 In 0 . 5 -Te at 973 and 1073 K. The enthalpy surface in the ternary system is determined by a valley of exothermic minima stretching from a minimum at the composition Ga 2 Te 3 to a minimum at composition In 2 Te 3 in the binaries. The excess enthalpies in the binary systems were adapted using the Lukas program. Ternary interactions were taken into account for the analytical description of excess enthalpies of the ternary system.
