Perovskite is a calcium titanium oxide mineral with a chemical composition of CaTiO3. It is named after the Russian mineralogist Lev Perovski (1792–1856). Perovskite is a brown to black mineral with a metallic luster and a vitreous to pearly luster. Perovskite occurs in igneous and metamorphic rocks and in sedimentary rocks as an alteration product of ilmenite. It is an important ore of titanium and a major source of refractory materials.
Some of the emerging trends in the field of perovskite materials include the development of novel synthesis methods, the exploration of new compositions, and the study of their optoelectronic properties.
