Perovskite (pronunciation: / p ə ˈ r ɒ v s k aɪ t /) is a calcium titanium oxide mineral composed of calcium titanate (chemical formula Ca Ti O 3).Its name is also applied to the class of compounds which have the same type of crystal structure as CaTiO 3, known as the perovskite structure, which has a general chemical formula A 2+ B 4+ (X 2−) 3.

Calcium titanate is an inorganic compound with the chemical formula Ca Ti O 3. As a mineral, it is called perovskite , named after Russian mineralogist, L. A. Perovski (1792-1856). It is a colourless, diamagnetic solid, although the mineral is often coloured owing to impurities.
Calcium copper titanate (also abbreviated CCTO, for calcium copper titanium oxide) is an inorganic compound with the formula CaCu 3 Ti 4 O 12. It is noteworthy for its extremely large dielectric constant (effective relative permittivity ) of over 10,000 at room temperature.
Titanite crystal model. Titanite, or sphene (from Ancient Greek σφηνώ (sphēnṓ) 'wedge'), [5] is a calcium titanium nesosilicate mineral, Ca Ti Si O 5. Trace impurities of iron and aluminium are typically present. Also commonly present are rare earth metals including cerium and yttrium; calcium may be partly replaced by thorium. [6]

In chemistry, titanate usually refers to inorganic compounds composed of titanium oxides, or oxides containing the titanium element. Together with niobate, titanate salts form the Perovskite group. In some cases, the term is used more generally for any titanium-containing anion, e.g. [TiCl 6] 2− and [Ti(CO) 6] 2−. This article focuses on ...
