Perovskite is a 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 ( A B X 3), known as the perovskite structure. Many different cations can be embedded in … Ver mais The mineral was discovered in the Ural Mountains of Russia by Gustav Rose in 1839 and is named after Russian mineralogist Lev Perovski (1792–1856). Perovskite's notable crystal structure was first described by Ver mais The eponymous Perovskite CaTiO3 crystallizes in the $${\displaystyle Pbnm}$$ space group (No. 62) with lattice constants Perovskites have a … Ver mais • Post-perovskite • Silicate perovskite Ver mais • "Perovskite" .
