Thermodynamic properties of Ba1-xLaxCoO3

Defect-Induced Properties and Thermodynamics of La0.5Ba0.5CoO3–δ

“…Indeed, as seen in Fig. 7, the values of C P (La 0.5 Ba 0.5 CoO 2.99 ) measured in the present work are lower than the heat capacity values of Gaur et al 18 at least at lower temperatures.…”

“…7), especially taking into account that Thakur et al 48 reported C , V so C P values recalculated from their data should be even higher due to the thermal expansion of the crystal lattice. Therefore, it can be expected that C P of La 0.5 Ba 0.5 CoO 3 calculated by the same research group 18,48 would also be overestimated. Indeed, as seen in Fig.…”

“…However, the knowledge of the fundamental thermodynamic properties of the compounds involved is necessary for making such analysis. In this respect, it has to be noted that thermodynamic properties of La 0.5 Ba 0.5 CoO 3-δ are still lacking: the heat capacity of La 0.5 Ba 0.5 CoO 3 was calculated only at low temperatures, 18 and the formation enthalpy of La 0.5 Ba 0.5 has not yet been reported.…”
