Abstract

For the first time the heat capacities of compound Bi12.5Er1.5CoO22.3 have been measured in the temperature range of 193–547 K. Differential scanning calorimetry has been used for measurements. The temperature dependence of heat capacity has been well described by a polynomial Co p,m (T) = 665.46 + 0.82227 T − 3.9692·10−4 T2 − 5.3798·106/T2. On the basis of smoothed heat capacities the enthalpy and entropy increments have been calculated (T = 193–547 K).
