  At present, there are mainly two kinds of performance improvement: piezo electric disc is doping modification; the other is new preparation process. Among them, the most piezo disc element is studied by researchers is doping modification. Although the application of leaded piezoelectric ceramics has become more and more mature, due to the poisonousness of Pb, piezo ceramic cylinder is harmful to the human body, the search for lead-free piezoelectric ceramics has also become a trend for the future development of piezoelectric ceramics. The performance of leaded piezoelectric ceramics is improved, and the piezoelectricity, temperature stability and Curie temperature of binary lead zirconate titanate Pb (ZrxTi1-x) O3 (PZT) piezoelectric ceramics are greatly superior to other ceramics. 

  More importantly, Piezo cylinder transducer can also adjust its electro-physical properties to a wide range by changing components or changing external conditions, such as ternary systems, quaternary systems, etc., to adapt to different needs. Therefore, lead-containing piezoelectric ceramics has become a hot topic for scholars at home and abroad. PZT-based piezoelectric ceramics generally have a relatively high sintering temperature of 1 200 to 1 300 C, at which point PbO is easily volatilized,piezo ceramic ring is affecting the structure and properties of piezoelectric products. In order to improve the piezoelectric properties of lead-containing solid solution ceramics, piezoelectric plate sensor is doping methods are used to replace the original constituent elements for modification. By increasing the electromechanical coupling coefficient K, the dielectric constant ε, and the mechanical quality factor Qm, materials satisfying different conditions of use are obtained.
