Barium titanate (BTO) is an inorganic compound with chemical formula BaTiO 3. 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 piezoelectric ceramic material that exhibits the photorefractive effect.

BaTiO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional.

Barium titanate is available in powder or crystal forms which have a perovskite structure. The structure of solid Barium titanate may vary with temperature. They can exist in five different phases, from low temperature to high temperature: rhombohedral, orthorhombic, tetragonal, cubic and hexagonal.

2013年2月20日 · effect on barium titanate based ferroelectric oxide thin films become essential. The fundamental investigation and development of these effects on the film growth mechanism become more important to develop an understanding of the relationship between microstructure and properties for thin films.

2023年8月24日 · Let us consider one of the most well-known ferroelectrics, barium titanate, (BaTiO 3). It has this perovskite structure: The temperature at which the spontaneous polarisation disappears is called the Curie temperature, T C. Above 120°C, barium titanate has a cubic structure. This means it is centro-symmetric and possesses no spontaneous dipole.

In ceramic composition and properties: Crystal structure. However, in barium titanate (BaTiO 3), shown in the figure, the central Ti 4+ cation can be induced to move off-centre, leading to a noncubic symmetry and to an electrostatic dipole, or alignment of positive and negative charges toward opposite ends of the structure. This dipole is ...
