Core Technology: Perovskite

Perovskite refers to a class of ceramic oxides with the general molecular formula AB03. These oxides were first discovered as the compound calcium titanate (CaTiO3) present in the mineral perovskite, hence the name. Due to their unique structural properties, these compounds are widely studied and applied in condensed matter physics. Consequently, physicists and chemists often refer to them by the ratio of their molecular formula (1:1:3), hence the alternative name "113 structure." They exhibit cubic crystal morphology, and in cubic crystals, parallel striations along the crystal edges are commonly observed. These striations result from the transformation of high-temperature polymorphs into low-temperature polymorphs, leading to the formation of polysynthetic twinning.

Perovskite is named after Russian geologist Lev Perovski, and its structures typically include simple perovskite, double perovskite, and layered perovskite. The chemical general formula for simple perovskite compounds is, where X usually refers to smaller cations or anions. Double perovskite structures have the composition formula, while layered perovskite structures are more complex and extensively studied, including those with the general formula as well as superconducting and trigonal layered perovskites. The most studied perovskite-type compounds are those with the composition.
