WebDec 25, 2024 · What is the general formula for a perovskite? When doped with different cations, a general formula for perovskites is A X A′ 1−X B Y B′ 1−Y O 3−δ, where δ is the concentration of oxygen vacancies in the structure, and x and y vary from zero to one. READ ALSO: What are the two types of cultural conflicts? A perovskite is any material with a crystal structure following the formula ABX3, which was first discovered as the mineral called perovskite, which consists of calcium titanium oxide (CaTiO3).
