Piezoelectric Ceramics

Piezoelectric Ceramics

 

piezoelectric materials obtained through the methods of ceramic technology from ferroelectric compounds. During the process of preparation, piezoelectric ceramics are subjected to an external electric field, and as a result, the ferroelectric domains are oriented in such a way as to give rise to a remanent polarization. Articles made of piezoelectric ceramics are either pressed from powder-like masses or cast from plastic masses (see). The firing of piezoelectric ceramics is done at 1200°-1350°C. A proposed method for preparing the raw powders involves the simultaneous chemical precipitation of constituents, which, because of their homogeneity of composition, will improve and stabilize the piezoelectric properties of the ceramics. Piezoelectric ceramics are used, for example, in the manufacture of ultrasonic radiators and detectors and in high-voltage generators.
