                  Important Facts That You Should Know About Ultrasonic Piezo Ceramic

  All materials are influenced by the composition through the structure to affect its performance. In the preparation of all materials, the composition-process structure properties are always closely related. The piezoelectricity of the material is also closely related to its internal microstructure related relations. With the further understanding of the piezoelectricity PZT-4 piezo ceramics materials and the extensive application of piezoelectricity in daily life and production, 10 Khz piezo disc crystal piezoelectric ceramics have developed into a series of products that involves a series of research and development topics. Some piezoelectric disc datasheet is under the action of external force to produce deformation, the relative displacement of charged particles, resulting in the binding surface charge crystal, this phenomenon is called the piezoelectric effect. Some PZT-5 piezo ceramics media under mechanical pressure, even if the pressure is as small as the sound wave vibration as small, which will produce compression or elongation and other shape changes, causing the dielectric surface charge, which is the positive piezoelectric effect; on the other hand, the application of excitation electric field, the medium will be produced mechanical deformation, which is called inverse piezoelectric effect; this property of the PZT-8 piezo ceramics crystal is called piezoelectric. The piezoelectric effect reflects the coupling between the elastic and dielectric properties of the crystal. Piezoelectricity was discovered on the quartz crystals of the Curie brothers. A few months later, they also verified the inverse piezoelectric effect experimentally, that is, the crystal would have strain and stress when an electric field was applied to the crystal. Piezoelectric ceramic materials barium titanate has been made in the United States, the former Soviet Union and Japan, barium titanate piezoelectric ceramic device was born.
