PbTiO3 (Lead Titanate)

PbTiO₃, or lead titanate, is a ceramic material that exhibits strong piezoelectric and ferroelectric properties, meaning it can generate electric charge under mechanical stress and retain electric polarization. It has a perovskite crystal structure, which contributes to its useful electrical behaviors. These properties make PbTiO₃ valuable in applications like sensors, actuators, and non-volatile memory devices. It is also a key component in the development of advanced electronic and optical devices, benefiting from its stability, high dielectric constant, and ability to switch electrical polarization with an external electric field.
