How to form a piezoelectric ceramic polarization device

Common applications of piezoelectric ceramics, in general, applications for positive and negative piezoelectric effects, as well as piezoelectric ceramic buzzers, piezoelectric ceramic loudspeakers, piezoelectric ceramic pickups, piezoelectric ceramic igniters, and pressure sensor. This one of the piezoelectric transformers is very common.

As for piezo ceramic disc polarization device, which is generally carried out in a silicone oil,which is applied with high voltage on both sides of the PZT piezo crystal, so that an electric field can be formed to polarize it. Further, a piezoelectric ceramic polarization device is formed to perform polarization operation, processing, and the like for the purpose of use.

D31 and D33 in piezoelectric discs transducer refers to the piezoelectric strain constant of piezoelectric ceramics. However, it should be noted that the corresponding test direction and the specific value are different. Therefore, I hope that everyone can pay attention to prevent mistakes, thus bringing unnecessary problems or troubles.

The Curie temperature of piezoelectric ceramics, in terms of specific values, is mainly seen in system. In addition, it should be noted that if it is lead-containing, it is 600C, and if it is lead-free, it is 200-300C.

Audio piezoelectric ceramic sensor film, which is also an application of piezoelectric ceramics, so we also need to know about it, its shape has many types, according to different environments and requirements, it is possible to choose a suitable one.However, in general, it has a square shape, a circular shape, a rectangular shape, and the like, and is 0.1 to 0.3 mm in the thickness.
