The ABX3 Perovskite Structure
1.1 Perovskites
Perovskite is a mineral of formula CaTiO3. It was discovered in 1839 by the Prussian mineralogist Gustav Rose in mineral deposits in the Ural Mountains and named after the Russian mineralogist Count Lev Aleksevich von Petrovski. Natural crystals have a hardness of 5.5–6 and a density of 4000–4300 kg m−3. They are usually dark brown to black, due to impurities, but when pure are clear with a refractive index of approximately 2.38. The crystal structure of this compound, initially thought to be cubic, was later shown to be orthorhombic (Table 1.1).
