The heat capacity and the heat content of bismuth niobate BiNb5O14 were measured by the relaxation time method, DSC and drop method, respectively. The temperature dependence of heat capacity in the form Cpm=455.84+0.06016T–7.7342·106/T2 (J K–1 mol–1) was derived by the least squares method from the experimental data. Furthermore, the standard molar entropy at 298.15 K Sm=397.17 J K–1 mol–1 was...
