Description: 

Piezoelectric ceramics are a class of electronic ceramic materials with piezoelectric properties. The main difference from a typical piezoelectric quartz crystal that does not contain ferroelectric components is that the crystal phases that make up its main components are all ferroelectric crystal grains. Since ceramics are polycrystalline aggregates with randomly oriented grains, the spontaneous polarization vectors of individual ferroelectric grains in them are also chaotically oriented. In order to make the ceramics exhibit macroscopic piezoelectric properties, it is necessary to place the piezoelectric ceramics under a strong DC electric field for polarization treatment after the piezoelectric ceramics are fired and coated with electrodes on the end faces, so as to make the original chaotically oriented respective generators. The transformation vector is preferably oriented along the direction of the electric field. After the polarization treatment of piezoelectric ceramics, after the electric field is cancelled, a certain macroscopic remanent polarization will be retained, so that the ceramics have certain piezoelectric properties.
