The excess enthalpies of liquid alloys in the ternary system Bi-Sb-Se were
determined at 873 K in a heat flow calorimeter for five sections BiySb1 - S
e-y with y = 0.2, 0.4, 0.5, 0.6 and 0.8 and for the section Bi0.5Sb0.5-Se a
t 773 K. The enthalpy surface in the ternary system is determined by a vall
ey of exothermic minima stretching from 2 : 3 compositions Bi2Se3 to Sb2Se3
in the Liquid binaries. The excess enthalpies in the binary systems were a
dapted with the association model using the Lukas program. Ternary interact
ions were taken into account for the analytical description of the ternary
system. (C) 1999 Elsevier Science B.V. All rights reserved.
