Perovskites

Perovskite (pronunciation: ) is an orthorhombic calcium titanium oxide mineral composed of calcium titanate (chemical formula ). Its name is also applied to the class of compounds which have the same type of crystal structure as , known as the perovskite structure, which has a general chemical formula for chalcogen (group 16) perovskites, or for the halogen (group 17) perovskites (the kind typically found in modern photovoltaics like photodiodes and solar panels). Many different cations can be embedded in this structure, allowing the development of diverse engineered materials.

perovskite compound

Davemaoite is a high-pressure calcium silicate perovskite (CaSiO3) mineral with a distinctive cubic crystal structure. It is named after geophysicist Ho-kwang (Dave) Mao, who pioneered in many discoveries in high-pressure geochemistry and geophysics.

chemical compound

Post-perovskite (pPv) is a high-pressure phase of magnesium silicate (MgSiO3). It is composed of the prime oxide constituents of the Earth's rocky mantle (MgO and SiO2), and its pressure and temperature for stability imply that it is likely to occur in portions of the lowermost few hundred km of Earth's mantle.
