Abstract

Abstract The enthalpies of mixing in liquid Ag – Ca, Ag – Eu and Ag – Yb alloys were measured by isoperibolic calorimetry at 1300 K. The experimental data were used to calculate the mixing enthalpies within the total composition region. The results of the investigation show exothermic effect of alloy formation. The minimum integral enthalpies of mixing are – 23.5 ± 1.0 kJ · mol – 1 (the Ag – Ca system); –16.5 ± 1.5 kJ · mol – 1 (the Ag – Eu system) and – 21.5 ± 1.9 kJ · mol – 1 (the Ag – Yb system) and are located in the silver-rich composition regions.
