Type PZS 51 and PZS 53
These materials are characterized by relativety high Curie temperatures (>350oC), low mechanical QM factor and high electrical resistivity at elevated temperatures. Type PZS 51 has a high dielectric constant, high charge coefficients and high electromechanical coupling coefficients.
Type PZ 55
This material has a lower Curie temperature, high dielectric constant, and high coupling coefficient.
Ceramics from these compositions are particularly useful in low resonant applications, pressure sensors, accelerometers, receivers, flow meters, NDT, sonic and ultrasonic transducers in air, medical instrumentation, sensitive detectors and actuators.
Type PZS 40, PZS
80, and PZS 41
These materials are characterized by relativety high coercive field, high mechanical QM factor and low dielectric loss. PZS 40 has a very low dielectric constant. PZS 40, PZS 80, and PZS 41 are high power and low loss materials.
Typical applications include underwater applications, high voltage generators, high power ultrasonics, e.g. cleaning, welding and drilling devices.
