Main purpose:1. Sound converter: sound converter is one of the most common applications. Like pickup, microphone, earphone, buzzer, ultrasonic depth detector, sonar and ultrasonic flaw detector of materials, piezoelectric ceramics can be used as sound converter. For example, the buzzer on children's

Commonly used piezoelectric ceramics include barium titanate system, lead zirconate titanate binary system and ternary system composed of adding a third ABO3 (a represents divalent metal ions, B represents tetravalent metal ions or the sum of several ions is positive tetravalent) compounds to the bi

Piezoelectric ceramics is a kind of information functional ceramic material piezoelectric effect, which can convert mechanical energy and electrical energy into each other. Piezoelectric ceramics not only have piezoelectric, but also have dielectric and elasticity. They have been widely used in medi
