|Abstract:||The low-temperature heat capacity of uvarovite (Ca3Cr2Si3O12) was measured between 2 and 400 K, and thermochemical functions were derived from the results. The measured heat-capacity curve shows a signiÞ cant lambda-shaped anomaly peaking at around 9 K. The nature of this transition is unknown. From our data, we suggest a standard entropy for uvarovite at 298.15 K of 320.9 ± 0.6 J/(mol·K).|
