PZT Powder Description

PZT Powder is a high-performance base material for advanced piezoelectric devices, produced with precise compositional control and microstructural engineering to deliver excellent piezoelectric, dielectric, and stability properties. Based on the lead zirconate titanate (PZT) system, its crystal structure is optimized through phase boundary regulation and doping to ensure high electromechanical coupling and low loss. Hard PZT powders feature dense grain boundaries for enhanced strength and power handling, with models like HMP42, HMP44, and HMP46 offering dielectric constants of 1200–1380 and kp≥0.59. Soft PZT powders improve lattice flexibility via ionic doping, reaching dielectric constants up to 4500, large piezoelectric strain (d33≥680×10⁻¹² C/N), and kt up to 0.78, as in HMP5A, HMP51, and HMP5H. Suitable for underwater transducers, ultrasonic equipment, sensors, and precision actuators, PZT Powder is an ideal choice for high-efficiency, high-performance piezoelectric components.
