Perovskite (structure)A perovskite is a crystalline material of formula ABX3 with a crystal structure similar to that of the mineral perovskite, this latter consisting of calcium titanium oxide (CaTiO3). The mineral was first discovered in the Ural mountains of Russia by Gustav Rose in 1839 and named after Russian mineralogist L. A. Perovski (1792–1856). In addition to being one of the most abundant structural families, perovskites have wide-ranging properties and applications.
Barium titanateBarium titanate (BTO) is an inorganic compound with chemical formula BaTiO3. It is the barium salt of metatitanic acid. Barium titanate appears white as a powder and is transparent when prepared as large crystals. It is a ferroelectric, pyroelectric, and piezoelectricceramic material that exhibits the photorefractive effect. It is used in capacitors, electromechanicaltransducers and nonlinear optics.
Titanium dioxideTitanium dioxide, also known as titanium(IV) oxide or titania, is the inorganic compound derived from titanium with the chemical formula TiO2. When used as a pigment, it is called titanium white, Pigment White 6 (PW6), or CI 77891. It is a white solid that is insoluble in water, although mineral forms can appear black. As a pigment, it has a wide range of applications, including paint, sunscreen, and food coloring. When used as a food coloring, it has E number E171.
PerovskitePerovskite (pronunciation: ) is an orthorhombic calcium titanium oxide mineral composed of calcium titanate (chemical formula CaTiO3).
Calcium oxideCalcium oxide (formula: CaO), commonly known as quicklime or burnt lime, is a widely used chemical compound. It is a white, caustic, alkaline, crystalline solid at room temperature. The broadly used term lime connotes calcium-containing inorganic compounds, in which carbonates, oxides, and hydroxides of calcium, silicon, magnesium, aluminium, and iron predominate. By contrast, quicklime specifically applies to the single compound calcium oxide.
Yttrium barium copper oxideYttrium barium copper oxide (YBCO) is a family of crystallinechemical compounds that display high-temperature superconductivity; it includes the first material ever discovered to become superconducting above the boiling point of liquid nitrogen [77 K (−196.2 °C; −321.1 °F)] at about 93 K (−180.2 °C; −292.3 °F).
Inorganic compoundAn inorganic compound is typically a chemical compound that lacks carbon–hydrogen bonds—that is, a compound that is not an organic compound. The study of inorganic compounds is a subfield of chemistry known as inorganic chemistry. Inorganic compounds comprise most of the Earth's crust, although the compositions of the deep mantle remain active areas of investigation. All allotropes of carbon and some simple carbon compounds are often considered inorganic.

TitaniumTitanium is a chemical element; it has symbol Ti and atomic number 22. Found in nature only as an oxide, it can be reduced to produce a lustrous transition metal with a silver color, low density, and high strength that is resistant to corrosion in sea water, aqua regia, and chlorine. Titanium was discovered in Cornwall, Great Britain, by William Gregor in 1791 and was named by Martin Heinrich Klaproth after the Titans of Greek mythology.
Lev PerovskiCount Lev Alekseyevich von Perovski (Russian: Лев Алексе́евич Перо́вский, also transliterated as Perofsky, Perovskii, Perovskiy, Perovsky, Perowski, and Perowsky; also credited as L.A. Perovski) (9 September 1792 – 21 November 1856) was a Russian nobleman and mineralogist who also served as Minister of Internal Affairs under Nicholas I of Russia. In 1845, he proposed the creation of the Russian Geographical Society.
OxideAn oxide () is a chemical compound containing at least one oxygen atom and one other element in its chemical formula. "Oxide" itself is the dianion (anion bearing a net charge of −2) of oxygen, an O2− ion with oxygen in the oxidation state of −2. Most of the Earth's crust consists of oxides. Even materials considered pure elements often develop an oxide coating.
DiamagnetismDiamagnetism is a form of magnetic response in materials that describes the property being repelled by an applied magnetic field; application of such creates in them an induced magnetic field in the opposite direction, thus causing a repulsive force. In contrast, paramagnetic and ferromagnetic materials are attracted by a magnetic field.
Sol–gel processIn materials science, the sol–gel process is a method for producing solid materials from small molecules. The method is used for the fabrication of metal oxides, especially the oxides of silicon (Si) and titanium (Ti). The process involves conversion of monomers or oligomers in solution into a colloidal solution (sol) that acts as the precursor for an integrated network (or gel) of either discrete particles or network polymers. Typical precursors are metal alkoxides.*As an Amazon Associate I earn from qualifying purchases.
