Ahshact-The heat capacity of synthetic andradite garnet (Ca~Fe&Oir) was measured between 9.6 and 365.5 K by cryogenic adiabatic calorimetry and from 340 to 990 K by differential scanning calorimetry. At 298.15 KC&,, and Sz arc 351.9 + 0.7 and 316.4 rf: 2.0 J/(mol-K), respectively. Andradite has a X-peak in Ci, with a maximum at 11.7 t 0.2 K which is presumably associated with the antiferromagnetic ordering of the magnetic moments of the Fe-‘+ ions. The Gibbs free energy of formation, ArGz (298…

Estimating the thermodynamic properties ( AGP and AIl 8 ) of silicate minerals at 298 K from the sum of polyhedral contributions
Many physical properties of silicate minerals can be modeled as a combination of basic polyhedral units (Hazen, 1985, 1988). It follows that their thermodynamic properties could be modeled as the sum
