摘要: The low-temperature heat capacity of magnesioferrite (MgFe2O4) was measured between 1.5 K and 300 K, thermochemical functions were derived from the results. No anomaly observed. From our data, we suggest a standard entropy (298.15 K) for 120.8±0.6 J mol−1 K−1, which is about 2.4 K−1 higher than previously reported calorimetric studies; but in rough agreement with predictions sets internally consistent thermodynamic data.
