Overview

Perovskite (pronunciation: ) is an orthorhombic calcium titanium oxide mineral composed of calcium titanate (chemical formula CaTiO3). Its name is also applied to the class of compounds which have the same type of crystal structure as CaTiO3, known as the perovskite structure, which has a general chemical formula A2+B4+(X2−)3 for chalcogen (group 16) perovskites, or A1+B2+(X1−)3 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.

Identification characteristics

  • Mohs hardness 5.5
