Article abstract of DOI:10.1016/0021-9614(80)90139-1

The heat capacity of KAlO2 has been measured from 5 to 303 K by adiabatic calorimetry.High-temperature enthalpies were determined up to 1197.8 K by copper-block drop calorimetry.A reversible transition was found at 810 K with an enthalpy of transition of 1295 J mol^-1.The values at 298.15 K of C⁰_p, 0(T) - S⁰(0)>, and -0(T) - H⁰(0)>/T are calculated as 76.12, 85.55, and 40.76 J K^-1 mol^-1, respectively.These thermodynamic functions are also calculated from 5 to 1400 K.
