摘要：
The low-temperature heat capacity of knorringite garnet (Mg3Cr2Si3O12) was measured between 2 and 300 K, and thermochemical functions were derived from the results. The measured heat capacity curves show a sharp lambda-shaped anomaly peaking at around 5.1 K. Magnetic susceptibility data show that the transition is caused by antiferromagnetic ordering. From the C (p) data, we suggest a standard entropy (298.15 K) of 301 +/- A 2.5 J mol(-1) K-1 for Mg3Cr2Si3O12. The new data are also used in conjunction with previous experimental results to constrain a dagger H (f) A degrees for knorringite.
