Abstract

The partial and integral molar enthalpies of mixing of liquid Co-Li-Sn alloys were determined using drop calorimetry. The investigations were performed along six sections by the addition of lithium to mixtures with the compositions x Co/x Sn ≈ 2:98, x Co/x Sn ≈ 1:9, and x Co/x Sn ≈ 3:17 as well as by the addition of cobalt to mixtures with the compositions x Li/x Sn ≈ 3:17, x Li/x Sn ≈ 1:2, and x Li/x Sn ≈ 1:1 at a temperature of 1,173 K. The Co-Li-Sn system shows exothermic behavior of the integral molar enthalpy of mixing in the investigated concentration range. The integral molar enthalpy of mixing of liquid Co-Li system was calculated by Miedema's model to fit our measured ternary data using an extended Redlich-Kister-Muggianu model for substitutional solutions.
