Piezoelectric ceramics are a kind of polycrystals with piezoelectric properties and an important part of information functional piezoelectric ceramics. With the advantages of high electromechanical coupling coefficient, low price and easy mass production, piezoelectric ceramics have been widely used

Granulation is a process in which a porcelain PZT material parameter is mixed with a binder to prepare coarser particles (about 20 mesh/inch) having good fluidity. This kind of granule is called a pellet to show the difference.1) The role of granulationSince the ground porcelain powder of sensitive

What’s the polarization process of piezoelectric ceramicsThe polarization process of piezo ceramics refers to adding a strong DC electric field to the piezoelectric ceramic to align the domains in the ceramic in the direction of the electric field. Only the ceramics processed by the

The polarization direction and vibration direction of the piezoelectric ceramics are along the thickness direction. Therefore, the input and output part of the piezoelectric ceramic resonator of the thickness vibration mode piezoelectric ceramics are longitudinal vibration modes, and the thickness

Piezoelectric ceramic vibrators have a wide range of applications. Piezoelectric ceramic transformers and piezoelectric ceramic filters are processed or combined by piezoelectric vibrators in a certain way. The parameters of the piezoelectric ceramics transducer depends largely on the vibration of t
