Lead titanium zirconium oxide (Pb(Ti,Zr)O3)

Description:
Lead titanium zirconium oxide (Pb(Ti,Zr)O3), commonly referred to as PZT, is a perovskite-type ceramic material known for its piezoelectric and ferroelectric properties. It is a solid solution of lead titanate (PbTiO3) and lead zirconate (PbZrO3), allowing for tunable electrical properties by varying the ratio of titanium to zirconium. PZT exhibits a high dielectric constant and strong piezoelectric response, making it widely used in sensors, actuators, and transducers. The material typically has a tetragonal or rhombohedral crystal structure, depending on the composition and temperature, which contributes to its ferroelectric behavior. PZT is also characterized by its high mechanical strength and thermal stability, although it can be sensitive to environmental factors such as humidity and temperature. Due to its lead content, PZT poses environmental and health concerns, prompting research into lead-free alternatives. Overall, PZT remains a critical material in various applications, including medical ultrasound devices, automotive sensors, and electronic components.
