Description

technical field [0001] The invention relates to the technical field of dielectric materials, in particular to a ceramic material with high piezoelectric performance and a preparation method thereof. Background technique [0002] Piezoelectric ceramics are information functional ceramic materials 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 using their materials under the action of mechanical stress to cause the relative displacement of the internal positive and negative charge centers to cause polarization, resulting in the appearance of bound charges with opposite signs on the surface of the material, that is, the piezoelectric effect. It has sensitive characteristics. Ceramic...
