Approaches To Improve Your Piezoelectric Ceramic

Piezoelectric ceramics are widely used for pickup piezo transducer in many fields such as communications, home appliances, aviation, exploration and computer and are an important kind of functional materials. The past 10 years, with the rapid development of science and technology, many electronic and electrical equipment use piezo rings level sensor for the selection of piezoelectric devices are increasingly demanding, the use of the environment and the piezoelectric material has greater flexibility in some special areas. high temperature pzt material piezoelectric rings has become a top priority, such as industrial use of high-power ultrasonic devices, high temperature ultrasonic objects, high temperature objects vibration, acceleration and pressure measurement piezo sounder PZT materials must use high-temperature piezoelectric materials. In the automotive and aerospace industries, however, there is also a need to provide materials that have higher operating temperatures than existing materials such as vibration sensors built into automobiles, controller surfaces, and dynamic fuel injection nozzles of high performance piezoelectric transducer is operating at temperatures up to 300°C. In general, the scope of the bulk piezoelectric material is often limited to about half of its Curie temperature, in order to ensure the stability of the piezoelectric properties of the piezoelectric device to work properly. However, excellent performance, high temperature piezoelectric ceramic material is very small. This makes them for a long time, special high temperature ultrasonic atomizing piezoelectric devices have to use the production process is complicated, high cost piezoelectric single crystal material. Therefore, the development of high performance Curie point piezoelectric ceramic materials has become a top priority.
