• Ferroelectricity of piezoelectric ceramic crystals

  The polarization of some dielectrics is very special. In a certain temperature range, their dielectric constants are not constant, but vary with field strength, and after removing the external electric field, these dielectrics are not neutral. There is residual polarization. In order to be analogous

• piezoelectric effect and dielectric effect of piezoelectric ceramic

  The piezoelectric effect is that when some dielectrics are deformed by an external force in a certain direction, polarization occurs inside, and positive and negative opposite charges appear on the two opposite surfaces thereof. When the external force is removed, it will return to the uncharged sta
