• Performance test method of piezoelectric ceramic material

  Curie temperatureWhen the temperature is higher than the curie temperature (Tc), the piezoelectric ceramic is in the paraelectric phase, and the spontaneous polarization and piezoelectricity also disappear. At the Curie temperature, many physical properties of piezoelectric ceramic materials, such a

• Three polarization elements of piezoelectric ceramics

  Only under the action of the polarized electric field, the electric domains can be arranged along the direction of the electric field, so it is the main factor of the polarization condition. The higher the polarization electric field, the greater the effect of promoting the alignment of electric dom
