Description	Tepelné kapacity a přírůstky entalpie SrBi2Nb2O9 (SBN) a SrBi2Ta2O9 (SBT) byly měřeny relaxační metodou (2-150 K), kalorimetrií Calvetova typu (305-570 K) a vhazovací kalorimetrií (773-1373 K). (cs) The heat capacities and enthalpy increments of strontium bismuth niobate SrBi2Nb2O9 (SBN) and strontium bismuth tantalate SrBi2Ta2O9 (SBT) were measured by the relaxation method (2-150 K), Calvet-type heat-conduction calorimetry (305-570 K) and drop calorimetry (773-1373 K). The temperature dependences of non-transition heat capacities in the form Cpm = 324.47 + 0.06371T −5.0755x106/T2 JK−1 mol−1 (298-1400 K) and Cpm = 320.22 + 0.06451T−4.7001x106/T2 JK−1 mol−1 (298-1400 K) were derived for SBN and SBT, respectively, by the least-squares method from the experimental data. Furthermore, the standard molar entropies at 298.15K S◦m (SBN) = 327.15 +/- 0.80 and S◦m (SBT) = 339.23 +/- 0.72 JK−1 mol−1 were evaluated from the low-temperature heat capacity measurements.
