Thermodynamic Properties of Monoclinic Neodymium Orthotantalate M-NdTaO4

Thermodynamic Properties of Monoclinic Neodymium Orthotantalate M-NdTaO4

The isobaric heat capacity of neodymium orthotantalate M -NdTaO 4 was measured using adiabatic calorimetry in the temperature range 7–342 K. Smoothed heat capacity values were used to calculate the thermodynamic functions (entropy, enthalpy increment, and reduced Gibbs free energy) in the region 0–3...

Zusammenfassung:The isobaric heat capacity of neodymium orthotantalate M -NdTaO 4 was measured using adiabatic calorimetry in the temperature range 7–342 K. Smoothed heat capacity values were used to calculate the thermodynamic functions (entropy, enthalpy increment, and reduced Gibbs free energy) in the region 0–345 K with the contribution of low-temperature (
