A perovskite is a material that has the same crystal structure as the mineral calcium titanium oxide (also known as Perovskite). 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.
