As a new material that has emerged in recent years, piezoelectric ceramics are widely used in the manufacture of electronic products and laboratory research. The variation of the dielectric constant of piezoelectric ceramics is closely related to its structural characteristics and polarization mode.

Domain:Generally, the directions of spontaneous polarization of ferroelectrics are different, but in a small area, the spontaneous polarization directions of the respective unit cells are the same, and this small area is called a ferroelectric domain. The boundary wall between the two domains is cal
