Features and Usage

P-41

Binary system lead-zirconate-titanate(PZT) modified material. It has lower dielectric loss and mechanical internal friction, higher electro-mechanic coupling coefficient, dielectric constant and piezoelectric coefficient. Mainly used to make piezoelectric ceramic transducers for medical application, ultrasonic cutting, drilling, welding, cleaning, probing, medium- and small-sized sonar.

P-81

Binary system modified material. It features low dielectric loss in intensive field, great mechanical strength and stable electrical parameters. It is mainly used to make transducers for large-sized sonar, large cleaner, capable ultrasonic processing and emulsification.

P-85

Quarternary system piezoelectric ceramic material. It has not only a higher dielectric constant and electro-mechanical coupling coefficient, but also a high mechanical quality factor. So, it is especially suitable for making transducers for high power transmissions.

P-45

It has a double behavior of receiving and transmitting. Major properties are moderate. Used to make medium power transducers, which can be used for both receiving and transmitting.

P-43

High piezoelectric coefficient d33, g33, and high mechanical strength. Performance is stable after repeated pressurization. Dielectric constant is relatively large, especially suitable for making gas lighter, liquefying gas ignition, high-voltage power supply for artillery shell fuse.

P-51

High sensitivity and excellent time stability. Used for underwater sound transducer, sensor, accelerometer, pressure gauge and buzzer.

PMgN-51

It has very high dielectric constant and electro-mechanical coupling coefficient, and low mechanical quality factor. Time stability of each parameter is good. Suitable for microphone/receiver, pickup, electro-acoustics and filter.

PSnN-51

Main parameters are identical to p-51. It features high stability of Curie temperature. So, it is a highly sensitive transducer material for high temperature applications. It can be used in high temperature probing, thickness measurement, oil well surveying and high temperature flow meter.

PliS-51

It has higher electro-mechanical coupling coefficient and moderate dielectric constant, and high sensitivity. It is suitable for making various receiving-type transducers with good time stability and high sensitivity.
