|Abstract:||The heat capacity of the perovskites SrZrO3 and BaZrO3 have been measured in the temperature range (1.8 to 305) K. The results have been compared to previous measurements reported in literature in the (50 to 300) K range. Our results for SrZrO3 are in excellent agreement with literature in spite of different crystal structure of the samples, those for BaZrO3 are somewhat higher. The experimental data suggest a significantly lower heat capacity below 50 K than the extrapolation reported in literature and thus yield more accurate values for the standard entropies.|
