Low-temperature heat capacity of samarium zirconate (Sm2Zr2O7)

The heat capacity of Sm 2 Zr 2 O 7 is investigated for the first time over a temperature range of 60–300 K by adiabatic calorimetry. The values of heat capacity, entropy, enthalpy, and reduced Gibbs energy are determined in standard conditions: C ° p (298.15 K) = 236.21 ± 0.94 J ⋅ mol. −1 ⋅ K −1 ; S °(298.15 K) = 247.3 ± 2 J ⋅ mol. −1 ⋅ K −1 ; Φ′(298.15 K) = 114.9 ± 1.7 J ⋅ mol. −1 ⋅ K −1 ; H °(298.15 K) − H ° (0 K) = 39,479 ± 197 J ⋅ mol. −1 .
