Using a molten salt method, EMF measurements have been obtained for In-Sb,
Sb-Sn and In-Sb-Sn alloys. New DSC experiments on Sb-Sn system gave a confi
rmation of the proposed Sb-Sn equilibrium phase diagram. A thermodynamic de
scription of the ternary liquid in fair agreement with the experimental res
ults has been obtained from the geometrical Muggianu approach. (C) 2001 Els
