Piezoelectric ceramics is an information-functional ceramic material that can convert mechanical energy and electrical energy into each other. Piezoelectric effect. In addition to piezoelectricity, piezoelectric ceramics also have dielectric properties, elasticity, etc., and have been widely used in medical imaging. Acoustic sensors, acoustic transducers, ultrasonic motors, etc. Piezoelectric ceramics are made by the relative stress of the internal positive and negative charge centers under the action of mechanical stress, which causes the opposite ends of the material to have oppositely bound trapped charges, ie piezoelectric effect, and has sensitive characteristics. Ceramics are mainly used in the manufacture of ultrasonic transducers, hydroacoustic transducers, electroacoustic transducers, ceramic filters, ceramic transformers, ceramic discriminators, high voltage generators, infrared detectors, surface acoustic wave devices, electro-optic devices, In addition to being used in high-tech fields, it is used to serve people in daily life and to create a better life for people.
Piezoelectric ceramics are a class of electronic ceramic materials with piezoelectric properties. The main difference from typical piezoelectric quartz crystals that do not contain ferroelectric components is that the crystal phases that make up their main components are ferroelectric crystal grains. Since the ceramic is a polycrystalline aggregate in which the crystal grains are randomly oriented, the spontaneous polarization vector of each ferroelectric crystal grain is also chaotically oriented. In order for the ceramic to exhibit macroscopic piezoelectric characteristics, it is necessary to burn in the piezoelectric ceramic. After the end face is double-electrode, it is subjected to polarization treatment under a strong direct current electric field, so that the respective polarization vectors of the original chaotic orientation are preferentially oriented along the direction of the electric field. The piezoelectric ceramic after polarization treatment is in the electric field. After the cancellation, a certain macroscopic remnant polarization is retained, so that the ceramic has a certain piezoelectric property.
