Barium titanate (BaTiO3) is obtained from barium carbonate (BaCO3) and titanium dioxide
(TiO2). Barium titanate belongs to the group of electroceramics. It has ferroelectric properties with field strength-dependent relative permittivity and is used in PTCs, piezoelectric elements, ceramic capacitors and FRAMs, among other applications. The material has a pronounced hysteresis.
