what is perovskite
Perovskite (pronunciation: /pÉËrÉvskaÉªt/) is a calcium titanium oxide mineral composed of calcium titanate, with the chemical formula Ca Ti O 3.The mineral was discovered in the Ural Mountains of Russia by Gustav Rose in 1839 and is named after Russian mineralogist Lev Perovski (1792â1856).It lends its name to the class of compounds which have the same type of crystal structure as CaTiO 3 (XII A 2+ VI B 4+ X 2â 3) known as the perovskite structure.The perovskite crystal structure was first described by Victor Goldschmidt in 1926, in his work on tolerance factors.The crystal structure was later published in 1945 from X-ray diffraction data on barium titanate by Helen Dick Megaw.he mineral was discovered in the Ural Mountains of Russia by Gustav Rose in 1839 and is named after Russian mineralogist Lev Perovski (1792â1856). It lends its name to the class of compounds which have the same type of crystal structure as CaTiO 3 (XII A 2+ VI B 4+ X 2â 3) known as the perovskite structure.
