Taken at the Harvard Museum of Natural History. A perovskite is any material with the same type of crystal structure as calcium titanium oxide (CaTiO 3), known as the perovskite structure, or XII A 2+ VI B 4+ X 2â 3 with the oxygen in the face centers.he general chemical formula for perovskite compounds is ABX 3, where 'A' and 'B' are two cations of very different sizes, and X is an anion that bonds to both. The 'A' atoms are larger than the 'B' atoms.
