Description:
Piezoelectric ceramics is an information functional ceramic material that can convert mechanical energy and electrical energy to each other - piezoelectric effect. The main difference from typical piezoelectric quartz crystals that do not contain ferroelectric components is that the crystal phases that constitute 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 are also chaotically oriented. In order for the ceramics to exhibit macroscopic piezoelectric properties, it is necessary to place the piezoelectric ceramics under a strong DC electric field for polarization treatment after they are fired and coated with multiple electrodes on the end faces, so that the original disordered orientation of the respective electrodes The optimal orientation of the vectorization vector is along the direction of the electric field. After the polarization treatment, the piezoelectric ceramics will retain a certain macroscopic remanent polarization strength after the electric field is canceled, so that the ceramics have certain piezoelectric properties.
