Abstract
Abstract The paper presents results of calorimetric studies on the enthalpies of mixing and formation in the system lead–indium. The enthalpy of formation is negative and becomes more negative at higher composition. The partial enthalpy of formation of lead is negative but increases at higher composition. The partial enthalpy of formation of indium is also negative and decreases with increasing the composition. The enthalpy of formation displays a considerable temperature dependence which seems to be smaller than that observed for the enthalpy of formation in other systems.
