The heat capacities of LiNO3 and CsNO3 from 350 to 700 K

Experimental investigation and thermodynamic evaluation of the CsNO3-LiNO3-NaNO3 ternary system

“…The scattering of the experimental data is within ± 3%, except for the results of Maeso and Largo [68]. Data of these authors, obtained by DSC, are about 6% lower than those of Jriri et al [32] determined by the same method.…”

“…The fact that the heat capacity increases drastically with an increase in the temperature may be attributed to a phase transition. As for CsNO3 (II), the DSC results published by Maeso and Largo [68] are the lowest data in the temperature range (430 -610) K. The heat capacity of CsNO3 (I) determined by Satoh [64], using an ice calorimetric technique, is abnormally high compared to the other literature data. For lack of more experimental information, his data are considered inaccurate.…”

“…Low temperature heat capacity of CsNO3 has been determined by different authors [32,[64][65][66][67][68]. All data are gathered in the same plot (Fig.…”

“…The data of Jriri et al [32] are considered as more reliable because a great care was taken during their experiments to overcome most of practical challenges (calibrations, heat capacity of the empty calorimeter, sample purity and masses, oxidation and corrosion of interior of the calorimeter, etc.). Therefore, heat capacity obtained by Maeso and Largo [68] is rejected. On the other hand, one can notice that the data of Flotow et al [66] extrapolated from low temperature are consistent with those of Jriri et al [32].…”

“…High-temperature heat capacities of CsNO3 collected from literature data [32,64,65,67,68] are presented in Fig. 2.…”
