Figure 4 The crystal structure of katayamalite with layers stacked normal to (001). The SiO4 ring layers are connected by Ca atoms on one side and by Li, Ti and K atoms on other side. Pink, brown, green, orange and yellow represent SiO4 groups, Ca, Li, Ti and K atoms, respectively. Displacements ellipsoids are drawn at the 99.999% probability level. |
