Standard entropy of formation of SnMg2 at 298K

Thermodynamic modeling of the Mg–Sn–Zn ternary system

“…It can be seen that the excellent agreement is achieved between the calculated heat content of Mg 2 Sn and the experimental data [39,54]. However, the calculated heat capacity by Fries and Lukas [23] at low temperature deviates unreasonably from the experimental data [53,54] and the present calculated results. The similar case is also shown in the comparison of the calculated heat content of Mg 2 Sn by Fries and Lukas [23] with the experimental data [54] and the present calculated results.…”

“…9 and 10 show the calculated heat capacity and heat content of Mg 2 Sn in comparison with the experimental data [39,53,54] agrees well with the experimental data [53,54] at high temperature, while shows the slight deviation at low temperature. It can be seen that the excellent agreement is achieved between the calculated heat content of Mg 2 Sn and the experimental data [39,54].

“…The enthalpy of formation of Mg2Sn was measured by Kubaschewski and Evans [51], Beadmore et al [52] and Sommer et al [39]. In addition, the heat capacity of Mg2Sn in the temperature from 2 K to 300 K was determined by Jelinek et al [53] and Morishita and Koyama [54]. Moreover, the heat contents (HT-H298) of Mg2Sn were reported by Sommer et al [39] in high temperature range and by Morishita and Koyama [54] in low temperature range.…”

The experimental results [39,[48][49][50][51][52][53][54] are consistent with each other and thus were considered in the present optimization.…”

“…Since the heat capacity and heat content of Mg 2 Sn was determined by Jelinek et al [53] and Morishita and Koyama [54], the Gibbs energy of Mg 2 Sn can be given as:…”
