Abstract

Abstract: The heat capacity of perovskite-like layered titanates K 2La 2Ti 3O 10 and K 2Nd 2Ti 3O 10 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)].
