Heat Capacity and Standard Thermodynamic Functions of NaGdTiO4 and Na2Gd2Ti3O10 over the Range from (6 to 630) K

The heat capacities of layered perovskite-like oxides NaGdTiO4 and Na2Gd2Ti3O10 were measured by precision adiabatic vacuum calorimetry over the temperature range from T = (6 to 344) K and by differential scanning calorimetry over the temperature range from T = (320 to 630) K. The standard thermodyn...

Summary:The heat capacities of layered perovskite-like oxides NaGdTiO4 and Na2Gd2Ti3O10 were measured by precision adiabatic vacuum calorimetry over the temperature range from T = (6 to 344) K and by differential scanning calorimetry over the temperature range from T = (320 to 630) K. The standard thermodynamic functions: molar heat capacity C p,m °, enthalpy H°(T) – H°(5), entropy S°(T) – S°(5), and Gibbs energy of the compounds were evaluated from the experimental heat capacity temperature dependences over the range from T = (5 to 630) K.
