The heat capacity of neodymium aluminate NdAlO 3 has been measured by low-temperature adiabatic calorimetry from 4 to 420K, yielding S 0 (298.15K)=(99.3+/-0.3)JK - 1 mol - 1 . For temperatures up to 900K the heat capacity has been derived from enthalpy-increment measurements (520-880K) using high-temperature drop calorimetry. The two sets of calorimetric data are in excellent agreement and show no transition in the measured temperature range.
