Perovskite

Perovskite is a calcium titanium oxide mineral species composed of calcium titanate, with the chemical formula CaTiO3.

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).

It lends its name to the class of compounds which have the same type of crystal structure as CaTiO3 (XIIA2+VIIB4+X2–3) known as the perovskite structure. The perovskite crystal structure was published in 1945 from X-ray diffraction data on barium titanate by the Irish crystallographer Helen Dick Megaw (1907–2002).
