Soft PZT

High sensitivity or "soft" ceramics feature high sensitivity and permittivity, but under high drive conditions are susceptible to self heating beyond their operating temperature range . These materials are used in various pick-ups and sensors, low-power motor-type transducers, receivers, and low power generators.

PZT-5 Series

The PZT-5 series materials are "soft" PZT. They range in Curie temperatures from 165°C to 350°C. All these materials have been optimised for charge constants or coupling coefficients for specific applications. PZT-51, 52, 53 series is often used as the receiver or generator element in hydrophones, accelerometers, and vibration sensors. PZT-51, 52, 53 Series is a lead zirconate titanate with a high sensitivity, permittivity, and time stability. PZT5H series is used in sensitive receivers and applications requiring fine movement control. It has been used in a wide range of applications from hydrophones to ink jet printers. PZT5H Series provides extremely high permittivity, coupling, and piezoelectric constant.
