P8 P4 P5 Piezoceramic piezoelectric ceramics
Piezoelectric ceramics is a kind of information functional ceramic material that can convert mechanical energy and electrical energy to each other-piezoelectric effect. In addition to piezoelectricity, piezoelectric ceramics also have dielectric properties and elasticity. Acoustic sensors, acoustic transducers, ultrasonic motors, etc. Piezoelectric ceramics are made by using their materials to cause relative displacement of the positive and negative charge centers inside the material under the action of mechanical stress, resulting in polarization, resulting in the opposite signs of bound charges appearing on both ends of the material, that is, the piezoelectric effect. It has sensitive characteristics. Ceramics are mainly used to manufacture ultrasonic transducers, underwater acoustic transducers, electroacoustic transducers, ceramic filters, ceramic transformers, ceramic discriminators, high-voltage generators, infrared detectors, surface acoustic wave devices, electro-optical devices, In addition to being used in high-tech fields, ignition and detonation devices and piezoelectric gyros are used to serve people in daily life and work hard to create a better life for people.
we can customize the piezoelectric ceramic . please tell us specification you want, thank you .
