摘要: The low-temperature heat capacity of hercynite (FeAl2O4) was measured between 3 and 400 K, thermochemical functions were derived from the results. heat-capacity curve shows a small lambda-shaped anomaly peaking at around 13 K. From our data, we suggest standard entropy for 298.15 K 113.9 ± 0.2 J/(mol·K), which is some 7.6 J/(mol·K) higher than reported previously by calorimetric study that missed contributions lowtemperature anomaly.
