The molar enthalpies of formation of liquid ternary Bi-Fe-Sb alloys have been determined at 1065 K by direct reaction calorimetry using the drop method. Measurements were performed along two sections: X-Bi/X-sb = 1/9 and 1/4. The experimental calorimetric data and estimated values with a Redlich-Kister formulation are compared. (C) 2006 Elsevier B.V.
