WebFeb 1, 2010 · Fig. 2 presents the Kohn–Sham band structure of CdGeO 3 IV with the partial density of states per orbital, as well as a picture of the first Brillouin zone for guidance. The orthorhombic phase of cadmium germanate exhibits (see Fig. 2, top-left), according with the GGA calculations, a set of twelve bands between ‐ 19 and ‐ 12 eV, with dominant s … WebCdGeO3IV was confirmed to be stable up to 12 GPa and 1200 ~ C. Thus, CdGeO3 transforms in the order of pyrox- enoid, garnet, ilmenite and perovskite phases with increas- ing pressure in the present pressure-temperature range. Sev- eral runs at 1300~1400~ were attempted at around 10 GPa.

WebAt high pressures, CdGeO3 pyroxenoid transforms to garnet, then to ilmenite, and finally to perovskite. Enthalpies of transition among the four phases were measured by high temperature calorimetry. The entropies of transition and slopes of the boundaries were calculated using the measured enthalpies and free energies calculated from the phase …
