BaTiO3
semiconductor· BaTiO3
Barium titanate (BaTiO₃) is a ceramic perovskite compound that functions as a ferroelectric semiconductor, exhibiting strong spontaneous polarization and high dielectric permittivity. It is widely used in capacitors, actuators, and piezoelectric devices across consumer electronics, automotive, and industrial control systems, where its ability to generate mechanical deformation under electric field or electrical response under mechanical stress is exploited. Engineers select BaTiO₃ for applications requiring compact energy storage, precise positioning, or electromechanical conversion where its ferroelectric and piezoelectric response outperforms conventional ceramics.
