In the material with this name, a calcium inhabits the center of eight (*) TiO6 octahedra.
Layers of this structure are separated by rock-salt-like Bi2O2 layer in the Aurivillius phase, which is paired with the  Ruddleson-Popper and Dion-Jacobson phases. Goldschmidt developed his tolerance factor, t, to estimate the degree of  distortion in the cubic lattice of this material. The piezoelectric material PZT has this structure. Type-II superconductors  with this structure have the highest TC, including the first superconductor to have a critical temperature above the boiling  point of nitrogen, YBCO. In the material with this name, a calcium inhabits the center of eight (*) TiO6 octahedra. A high-  pressure form of magnesium silicate that likely occurs in the D-double prime layer is termed "post" this structure. For 10 points,  name this crystal structure of materials that follow the chemical formula ABX3, where A and B are cations and X is an anion.
