Thermodynamics of liquid CaAg and CaIn alloys

Thermodynamic description of the Ag–(Ca, Li, Zn) and Ca–(In, Li) binary systems

“…state) in the Ag-Ca liquid phase at 800°C is shown in Fig. 2 with experimental data from Delcet and Egan [32] and Fischbach [35] in comparison with the calculated data from Braga et al [31] and Huang et al [39]. The calculated enthalpy of mixing of liquid solutions at 1027°C is shown in Fig.…”

“…The activity of Ca in the liquid phase, the enthalpy of mixing, the Gibbs energy of mixing, and the entropy of mixing of the liquid solution at 800°C were reported by Delcet and Egan [32] based on EMF measurements employing CaF 2 as a solid electrolyte. The enthalpy of formation of compounds were determined by Notin and Hertz, and Notin et al [33,34] from EMF measurements employing CaF 2 as a solid electrolyte.…”

“…The activity of Ca in the liquid phase, and the mixing free Gibbs energies of liquid solutions at 800°C were derived by Delcet and Egan [73] from their EMF measurements. No experimental thermodynamic property data of solid phases was reported.…”

Partitioning of Calcium Between Liquid Silver and Liquid Iron

“…This, however, requires good knowledge of the thermodynamic properties of the silver-calcium system at the temperature of interest. Experimental measurements on the silver-calcium system over the whole composition range have been made at 1073 K to 1273 K (800°C to 1000°C), by Delcet and Egan [5] and Fischbach [6] using EMF technique and Knudsen effusion technique, respectively. Wakasugi and Sano [7] as well as Tago et al [8] measured the activity coefficient of calcium in liquid silver at low calcium contents in the temperature range 1570 K to 1831 K (1297°C to 1558°C) using CaC 2 -and CaO-saturated slags in equilibrium with liquid silver.…”
