50*17*5 ultrasonic piezoelectric ceramics ring for transducer

Piezoelectric ceramic is a kind of information functional ceramic material which can convert mechanical energy and electrical energy into each other. Piezoelectric ceramic has not only piezoelectric properties, but also dielectric and elastic properties. It has been widely used in medical imaging, acoustic sensors, acoustic transducers, ultrasonic motors and so on. Piezoelectric ceramics are made by using the material under the mechanical stress, which causes the relative displacement of the positive and negative charge centers and polarization, resulting in the opposite sign of bound charges on the surface of both ends of the material, that is, piezoelectric effect. Piezoelectric ceramics are mainly used to manufacture ultrasonic transducers, underwater acoustic transducers, electroacoustic transducers, ceramic filters, ceramic transformers and ceramics Frequency discriminator, high-voltage generator, infrared detector, surface acoustic wave device, electro-optical device, ignition and detonation, piezoelectric gyroscope, etc., besides being used in high-tech field, it is more to serve people in daily life and to create a better life for people.
