| Popis: | The heat capacity of perovskite-like layered titanates K2La2Ti3O10 and K2Nd2Ti3O10 is studied via precision adiabatic vacuum calorimetry in the temperature range of 7–350 K, and by differential scanning calorimetry in the range 350–670 K. Standard thermodynamic functions are calculated from experimental data on heat capacity in the temperature range of 9–670 K: enthalpy H(T) − H(9), entropy S(T) − S(9), and Gibbs function −[G(T) − G(9)]. |
