The PtIn system: Enthalpies of formation of liquid and solid alloys

Thermodynamic modeling of the In–Pt system

“…2a and b shows the calculated enthalpy of mixing of the liquid phase and the compound In 3 Pt 2 at 1373 K and 1320 K in the In-Pt system with the experimental data measured by Anres et al [29] and the predicted values by Colinet et al [30] and de Boer et al [31], respectively. The experimental work of Anres et al [29] indicated that the enthalpy of mixing of the liquid phase was not dependent on temperature. In the Fig.…”

“…3. Calculated standard enthalpy of formation in the In-Pt system at 298 K with the experimental data [27][28][29] and the predicted values [31]. The reference states are tetragonal for In and fcc for Pt.…”

“…The reference state is the liquid phase for In and Pt. (b) Calculated enthalpy of mixing of the liquid phase and the compound In 3 Pt 2 at 1320 K in the In-Pt system with the experimental data [29]. The reference state is the liquid phase for In and Pt.…”

“…The parameters obtained from the first treatment were used as starting values for the second treatment. [29] and the predicted values [30,31]. The reference state is the liquid phase for In and Pt.…”

“…Vogelbein et al [28] measured the enthalpies of formation of InPt 3 and fcc solution at 6 at.% In at 1000 K using calorimetry of dissolution. Anres et al [29] measured the enthalpies of mixing of liquid using high-temperature calorimeter in the composition range of 0 < x Pt < 0.599 at temperature range from 1247 K to 1467 K. At the same time, the enthalpy of formation of the compound In 3 Pt 2 at 1320 K was also determined by calorimetric measurements and some points of the liquidus were deduced from the calorimetric experiments [29].…”
