More info

PZT Powder is a high-performance piezoelectric material based on the lead zirconate titanate (PZT) system, designed for advanced transducers, sensors, and actuators. Hard types (HMP42, HMP44, HMP8) feature low dielectric loss, high Qm, and strong power handling for ultrasonic cleaning, sonar detection, and welding, while soft types (HMP5A, HMP51, HMP5H) provide high dielectric constant, large d33, and excellent sensitivity for precision actuation and reception. With a Curie temperature range of 200–320 °C and compatibility with both conventional (1260 °C) and low-temperature (985 °C) sintering, it delivers reliable performance and processing flexibility. Heeger Materials provides high-quality PZT powder for demanding piezoelectric applications.
