With a fully automated high temperature calorimeter, the enthalpy of format
ion of the ternary liquid system [In-Sn-Zn] has been measured at about T-e
= 713 K, over a large molar fraction range. From the enthalpy of formation
of the binary liquid systems [In-Zn], [Sn-Zn] and [In-Sn] previously publis
hed, the ternary enthalpies of formation have been estimated by using sever
al well-known relations. Calculated and experimental results have been comp
ared. (C) 2000 Elsevier Science B.V. All rights reserved.
