A description of the thermodynamic properties of pure indium in the solid and liquid states from 0 K

Investigation and development of programmable system on chip based differential scanning calorimeter for thermal analysis of materials

“…( 9). The typical melting point of indium was determined to be 156. the reported value of 156.6 ○ C. 24,25 The enthalpy of the melting of indium was obtained as 3.2551 kJ/mol, against the literature data of 3.264 kJ/mol. 26,27 The instrument was calibrated with standard high purity metals, namely, indium, zinc, aluminum, and silver, and the instrument constant was evaluated.…”

The Effect of Structural Change during the Activation Process on the Catalysis of In/SiO2 Nonoxidative Coupling of Methane: An Operando XAFS Study

“…If the Debye–Waller factors of the liquid-metal In and In–O could be calculated from the vibration frequency, ω, of the In–In and In–O bonds, as shown in eq : σ 2 = ℏ 2 μ ω cot h true( ℏ ω 2 k normalB T true) where μ and k B are the reduced mass and the Boltzmann constant, respectively, we could roughly estimate them (3) although eq is based on a harmonic approximation and it is less valid to apply such anharmonic systems. The ω for In–In in the liquid-metal phase has been reported to be 1.2 × 10 13 Hz . On the other hand, the ω for In–O has been reported to be 9.4 × 10 13 Hz, which is eight times larger than that for In–In.…”

“…The ω for In−In in the liquid-metal phase has been reported to be 1.2 × 10 13 Hz. 29 On the other hand, the ω for In−O has been reported to be 9.4 × 10 13 Hz, 30 which is eight times larger than that for In−In. The corresponding Debye−Waller factors (σ 2 ) at 1000 K calculated by eq 3 are 0.1 Å 2 (for In−In) and 0.01 Å 2 (for In−O).…”

The Physics of the Thermodynamic Entropy

“…There is nothing particular about the elements represented in Figure 4 other than that they have moderate to low melting points. They were otherwise chosen because an internet search produced a complete range of data for each of the three metals, aluminium [11], indium [12] and lead [13]. It is noticeable that, with the exception of lead, all four have a mean reduced heat capacity below three.…”

“…Transformation to constant volume is straightforward given knowledge of the compressibility as well as the thermal expansivity [7] and reduces the heat capacity slightly, but without doing the calculations it is not possible to say for certain that the mean reduced heat capacity at constant volume will stay below 3. [12], Al [11], Pb [13] and Si [8] from 0K to their respective melting points. The specific heat of Ge [10] is shown over a limited range of temperature range, but including the melting point, for direct comparison with silicon.…”
