Barium titanate oxide (BaTiO₃ or Ba₁Ti₁O₆-type perovskite) is a ceramic semiconductor compound belonging to the perovskite family, known for its ferroelectric and piezoelectric properties. Industrial applications include capacitors, thermistors, sensors, and actuators, where its high dielectric constant and ferroelectric behavior at room temperature make it valuable for energy storage and electromechanical transduction. This material is also of significant interest in research for photocatalysis, ferroelectric memory devices, and lead-free piezoelectric alternatives, offering advantages over legacy lead-containing compounds in electronic and electromechanical systems.
