Performance Of PZT8 Versus PZT4 Piezoceramic Materials In Ultrasonic Transducers

PZT8 and PZT4 are the common [hard" piezoceramic materials used in power ultrasonic transducers (e.g., welding, cutting, sonar, etc.). PZT8 is perceived as the better choice for resonant devices, primarily due to its higher mechanical quality factor Qm. PZT8 is also considered a [harder" material compared to PZT4, since it has better stability at higher preloads and drive levels.

Many PZT8 and PZT4 are the common [hard" piezoceramic materials used in power ultrasonic transducers (e.g., welding, cutting, sonar, etc.). PZT8 is perceived as the better choice for resonant devices, primarily due to its higher mechanical quality factor Qm. PZT8 is also considered a [harder" material compared to PZT4, since it has better stability at higher preloads and drive levels.

PZT4 is used in signal transmitting, it has clear advantages such as higher output (i.e., higher d33), mostly applications:sonar. underwater acoustic transmitter.
