Barium orthotitanate is heating pellets of Ba(OH) and TiO. Additionally, there are polymer precursor, sol-gel and reverse micellar routes to BaTiO synthesis. BaTiO has also been successfully grown as a thin film with chemical vapor deposition. Barium orthotitanate can remove up to 99.9% of from a high-temperature gas stream by the reaction: Barium orthotitanate Barium orthotitanate is the inorganic compound with the chemical formula BaTiO. It is a colourless solid that is of interest because of its relationship to barium titanate, a useful electroceramic. The solid has two known phases: a low-temperature (β) phase with "P"2/"n" symmetry and a high-temperature (α′) phase
Chemical element plants, the calcium in mollusc shells, or the iron in the hemoglobin in vertebrate animals' red blood cells. The concept of an "element" as an undivisible substance has developed through three major historical phases: Classical definitions (such as those of the ancient Greeks), chemical definitions, and atomic definitions. Ancient philosophy posited a set of classical elements to explain observed patterns in nature. These "elements" originally referred to "earth", "water", "air" and "fire" rather than the chemical elements of modern science. The term 'elements' ("stoicheia") was first used by the Greek philosopher Plato in about 360 BCE in his dialogue Timaeus,
