50205mm PZT-8 Piezoelectric Ceramic Ring For 2000W 20khz/15khz High Power Ultrasonic Transducer

Piezoelectric ceramics are different from quartz crystals in that the former is a polycrystalline piezoelectric material, while the latter is a single crystal. Piezoelectric ceramics do not have Piezoelectricity before polarization. After polarization treatment, the Piezoelectricity is very obvious and has a high pie…

50*20*5mm PZT-8 Piezoelectric Ceramic Ring For 2000W 20khz/15khz High Power Ultrasonic Transducer

Piezoelectric materials, including crystals and ceramics, generate voltage based on the applied mechanical stress. In the so-called inverse Piezoelectricity, these same materials become longer or shorter with the applied voltage.

The voltage, motion, and force generated by piezoelectric materials are very small and usually require amplification. For example, the size of a typical piezoelectric ceramic disk will only increase or decrease by a few tenths of a millimeter. Despite this slight change in thickness, it is still used as a driving element in some precision Optical instrument and CNC machine tools.

Piezoelectric ceramics are highly favored because they can be customized to meet specific requirements. At present, PZT (Lead zirconate titanate) material is the most widely used piezoelectric ceramics. Compared with other piezoelectric ceramics, they have higher sensitivity and higher operating temperature.
