Barium Titanate (BaTiO3)

Barium Titanate is a ferroelectric ceramic material that appears as white crystal powder, and as a grey ceramic when pressed and sintered into a sputtering target. The atomic structure of the material varies from cubic, tetragonal, orthorhombic, and rhombohedral crystal structures depending on the preparation technique. Regardless, all of these structures of BaTiO3 exhibit the ferroelectric effect. Due to the piezoelectric properties it exhibits, versatile ceramic is used in capacitors, microphones, transducers, and other acoustic devices. BaTiO3 even has uses in nonlinear optics where its ability to manipulate light with the photorefractive effect is utilized. However, its main use is in multi-layer ceramic capacitors (MLCCs) which are utilized in a wide range of electronic devices. The material undergoes phase changes at different temperatures, changing from a cubic to a tetragonal, orthorhombic, and then rhombohedral crystal structure as it cools from high temperatures. It begins to lose its permanent magnetic properties at around 120-130 ºC.
