The main role of the piezoelectric ceramic crystal during operation will be mechanically deformed with the number of changes in the voltage and frequency. On the other hand, when the piezoelectric ceramic is vibrated, an electric charge will be generated. Utilizing this principle, when an electric s

Piezoelectric ceramic resonators have a wide range of applications in many fields such as ultrasonic transducers, ceramic filters, piezoelectric accelerometers, and ceramic loudspeakers. In the traditional analysis and testing theory of piezoelectric ceramic resonators (including the international I

Lead zirconate titanate ceramics (PZT) have been widely used in polarized piezoelectric ceramic transducer due to their excellent properties. However, the piezoelectric ceramics are containing PZT have a relatively high sintering temperature of about 1200 °C. The oxidation temperature of lead oxide

1. Quartz crystal and piezoelectric ceramic, are these two the same in piezoelectric effect?Quartz crystals and piezoelectric ceramics, the piezoelectric effect of these two piezoelectric plate crystal, from a professional point of view, is not the same. Because there is no volumetric deformation pi

1. If the piezoelectric ceramic piece has been bonded to the copper , what should I do? In addition, about the capsulation, how to choose? For the first problem, the processing method of piezoelectric discs crystal is very simple. Just test whether the curie temperature of the piezoel

In a multi-frequency ultrasonic cleaner system, the ultrasonic cleaning transducer is one of the key components. It must have two resonant frequencies and the impedance near its resonance point should be close to achieve the best conversion of electricity and sound.The sandwich type piezoelectric ce
