Barium titanate (BaTiO₃) is a ferroelectric ceramic compound widely recognized as a classic perovskite material with exceptional piezoelectric and dielectric properties. It is employed across electronics, sensing, and actuator applications where its ability to generate electrical charge under mechanical stress or respond to electric fields is essential. Engineers select barium titanate over alternatives when high dielectric constant, piezoelectric coupling, and thermal stability are required in compact form factors, though it is typically used as a secondary phase in composites or thin films rather than as a monolithic bulk material in most modern applications.
