For the first time the heat capacities of phase Bi12.5Nd1.4In0.1ReO24.5 have been measured in the temperature range of 175-550 K. Differential scanning calorimetry has been used for measurements. The temperature dependence of heat capacity is well described by a polynomial C-p,m(o) (T) = 542.62 + 1.5107 T - 1.0402 . 10(-3) T-2 - 2.7875 . 10(6)/T-2. On the basis of smoothed heat capacities the enthalpy and entropy increments were calculated (T = 175-550 K). (C) 2016 Elsevier Ltd.
