Piezoelectric ceramic disc transducer applications:
The use of ferroelectric crystal structure of this feature can be fired after the ferroelectric ceramic at a certain temperature and time conditions, with a strong DC electric field processing, so that in the direction along the electric field shows a certain degree of net polarization. This process is called artificial polarization.
After polarization treatment, the sintered ferroelectric ceramics will become anisotropic from isotropic and thus have a piezoelectric effect. Thus, the piezoelectric effect of ceramics comes from the ferroelectricity of the material itself. Therefore, all the piezoelectric ceramics should also be ferroelectric ceramics.
