PZT4

PZT4 is a specific composition of lead zirconate titanate (Pb[ZrₓTi₁₋ₓ]O₃), a piezoelectric ceramic material. Piezoelectric materials exhibit the piezoelectric effect, meaning they generate an electric charge in response to applied mechanical stress, and conversely, deform when subjected to an electric field. PZT4 is characterized by a particular ratio of zirconium to titanium, typically around 52% Zr and 48% Ti, which places it near the morphotropic phase boundary. This specific composition is known for its high piezoelectric charge constant (d₃₃) and relatively high electromechanical coupling factor (kₚ), making it suitable for applications requiring significant mechanical displacement or force generation from an electrical input. It also exhibits good dielectric properties and mechanical strength. PZT4 is widely used in actuators, sensors, transducers, and sonar applications due to its robust performance and cost-effectiveness. Its operating characteristics, such as resonance frequency and operating temperature, depend on its geometry and the specific formulation. Compared to other PZT formulations, PZT4 is often favored for its balance of piezoelectric properties and durability in dynamic environments.
