Abstract
The low-temperature heat capacity, C p, of the crystalline and glassy forms of the mineral grossular Ca 3Al 2Si 3O 12 are distinctly different. The effect has been linked to differences in coordination of Al and the resulting structural roles of the ion in each phase. Inelastic neutron-scattering measurements for the glassy phase reveals an excess density of states below 30 meV and C p, calculated from the vibrational density of states agree with thermodynamic measurements. Static neutron-scattering data confirm that Al is tetrahedrally coordinated in the glass as distinct from octahedral coordination in the crystal.
