• Piezoelectric ceramics is one of those information handy ceramic materials which will convert mechanical energy and electricity to each other-piezoelectric effect. In addition to piezoelectricity, piezoelectric ceramics even have dielectric properties, elasticity, etc., and feature been broadly used in scientific imaging, Acoustic sensors, acoustic transducers, ultrasonic motors, etc. Piezoelectric ceramics are made during the use of their materials to cause relative displacement of the fine and unfavorable fee centers contained within the materials below the action of mechanical stress, leading to polarization, resulting in the opposite signs of certain fees acting on both ends of the material, that is, the piezoelectric effect. It has sensitive characteristics. Ceramics are mainly used to fabricate ultrasonic transducers, underwater acoustic transducers, electroacoustic transducers, ceramic filters, ceramic transformers, ceramic discriminators, high voltage generators, infrared detectors, surface acoustic wave devices, electro-optical instruments and In addition to being used in high-tech fields, piezoelectric ceramic are used to serve humans in daily life and work flat out to create a better existence for folks ceramics Alumina ceramics is maybe probably the most extensively used, maximum versatile, and best ceramic materials among oxide ceramics voltage is applied to piezoelectric ceramics, it is going to supply mechanical deformation with modifications in voltage and frequency. On the alternative hand, when the piezoelectric ceramic is vibrated, an electric fee is generated. Using this principle, when an electric signal is applied to a vibrator composed of 2 piezoelectric ceramics or a piezoelectric ceramic and a steel sheet, the so-called bimorph element, ultrasonic waves is probably emitted thanks to bending vibration. On the contrary, when ultrasonic vibration is applied to the piezoelectric bimorph element, an electric signal is generated. Based on the above effects, piezoelectric ceramics can be used as ultrasonic sensors ceramics are functional ceramic materials that may mutually convert mechanical calories and electric energy, and belong to inorganic non-metallic materials. At a similar time, it has a favorable and negative piezoelectric effect. The piezoelectric ceramic wafers produced by manner of Changzhou Ultrasonic Electronics Co., Ltd. are chiefly used in the fields of ultrasonic probes, ultrasonic clinical treatment, ultrasonic flowmeters, and automatic control. With perfect performance and total specifications, PZT piezoelectric wafers and new composite piezoelectric wafers can meet several kinds of needs.
