Piezoelectric ceramic prepares process for high-performance piezoelectric ceramic materials, we must first select the appropriate system components, and only under the premise of the appropriate composition ratio, it is possible to develop high-performance materials. The current preparation of piezoelectric ceramics is mainly modified by doping in barium titanate piezo bimorph actuator derived. The traditional production process does not fully adapt to the current performance of piezoelectric ceramics, especially for the development of lead-free piezoelectric ceramicsis even more so. With the successful application of the method, especially in the preparation of piezo discs and cylinders, it has now been possible to make fibrils using sol and gel methods.First, a sol and gel process is used to prepare chemical primary particles and then extruding the resulting gel slurry into fibers. The extruded fibers are aged and dried to obtain a monolithic fiber gel for piezo transducer datesheet. Liquid phase is sintering, but will be added to the initial sol at a heating rate, the atmosphere can be obtained with an average diameter of less than or equal to the pure fibers of these fibers,only pore distribution of the twin crystal piezo electric can be high electric field polarization, and reducing the intergranular stress caused by the large quadrilateral distortion during polarization. Piezoelectric ceramic oscillators used in oscillators, resonators, filters, piezoelectric couplers, mechanical filters, television communication equipment, computers, etc. With delay device, television cathode ray oscillography static electricity, electrosorption device in the pressure device.
