The Reasons Why We Love Piezoelectric Ceramics
Piezoelectric ceramic process requires the preparation of excellent performance piezoelectric ceramic materials, we must first select the appropriate system components as for piezoceramic transducer ring ceramic chip capacitors, only in the premise of the appropriate component ratio, it is possible to develop high-performance materials. The current preparation of piezoelectric ceramics is mainly modified by doping in barium titanate derived. The traditional production process does not fully adapt to the current performance of piezoelectric ceramics, especially for the development of lead-free piezoelectric ceramics Pzt chip electrode .With the successful application of sol and gel methods ,especially in the preparation of piezoeletric plate datesheet PZT-5, Now which has been able to do with fibrous sol and gel method. The chemical primary particles are first prepared by a sol and gel method and then the resulting gel slurry is extruded into fibers. After the extruded fibers are aged and dried, a monolithic fiber gel is obtained. In order to promote liquid-phase sintering, it is added to the initial sol of piezoelectric tube fiber actuator , and the average diameter is obtained by sintering in the atmosphere at a heating rate. These fibers have only a uniform distribution of twin-crystal microstructures and can be polarized with high electric fields and reduce the intergranular stress caused by large tetragonal distortions during polarization.
