PbTiO3, or lead titanate, is a ceramic material known for its strong piezoelectric properties, meaning it can generate an electric charge in response to mechanical stress. This makes it valuable in various applications, including sensors, actuators, and capacitors. Its perovskite crystal structure contributes to its unique electrical characteristics. In addition to its piezoelectric capabilities, PbTiO3 is also used in the production of ferroelectric materials, which can retain electric polarization even after the external electric field is removed. This property is useful in memory devices and other electronic components, enhancing their performance and efficiency.
