Description	Heat capacity and enthalpy increments of strontium niobates Sr2Nb10O27 (S2N5) and Sr5Nb4O15 (S5N2) were measured by the relaxation time method (2-275 K), DSC (253-353 K) and drop calorimetry (673-1371 K). Temperature dependencies of the molar heat capacity in the form Cpm = 835 + 0.23 T - 14x106/T2 J K-1 mol-1 for S2N5 and Cpm =511+0.14T - 6.6x106/T2 J K-1 mol-1 for S5N2 were derived by the least-squares method. The molar entropies at 298.15 K, S^o_m (S2N5, 298.15 K) = 759.7 JK-1 mol-1 and S^o_m (S5N2, 298.15 K) = 524.5 JK-1 mol-1,were evaluated from the lowtemperature heat capacity measurements.
