Study the Crystal Structure and Phase Transition of BaTiO – A Pervoskite

Abstract: Perovskites belong to one of the largest oxide families. The interesting physical properties and important
applications have been widely investigated in this system since the last century. Among the large perovskite family, one
of the most important groups is the ferroelectric oxide, which possesses extremely high values of dielectric constant and
low dielectric loss, as well as good dielectric tunability. Ferroelectricity has been known since the 1920s and
ferroelectricity in perovskite BaTiO3 (BTO) was first discovered in the 1940s. In the present work we have studied the
pervoskite nature of BaTiO3 (BTO) with its Crystal structure and phase transition.
