Figure 9
A selected subset of the CaZP unit cell illustrated with atom labels to depict the corner-sharing nature of the PO4 tetrahedra and ZrO6 octahedra for the (a) low temperature, (space group No. 148), and (b) high temperature, (space group No. 167). The Ca, Zr and vacancy in this subset lie along the c-unit cell axis. The same labeling scheme is used for SrZP. |
