1. Perovskite is a calcium titanium oxide mineral composed of calcium titanate (CaTiO3). It lends its name to the class of compounds which have the same type of crystal structure as CaTiO3 (XIIA2+VIB4+X2−3) known as the perovskite structure.

Generally, perovskite compounds have a chemical formula ABX3, where ‘A’ and ‘B’ represent cations and X is an anion that bonds to both. In perovskites, the ‘A’ cation is much larger than the ‘B’ cation. Perovskites have a cubic crystal structure, as represented in the diagram on the right (blue spheres represent the ‘A’ cations, black spheres represent the ‘B’ cations and red spheres represent the ‘X’ anions). Perovskite structures occur naturally as the minerals Perovskite, Loparite, and Bridgmanite.als Perovskite, Loparite, and Bridgmanite.
