(1) Dielectric constant εThe dielectric constant is a reflection of the dielectric properties of a material, or the nature of polarization, and is usually expressed . Piezoelectric ceramic components for different purposes have different dielectric constant requirements for piezoelectric ceramics. F

At first, we tried to measure the DC high-voltage gear of the ordinary pointer type multi-meter. It was found that the voltage of the two electrodes of piezoelectric ceramics can only slightly shake the pointer when the black plastic pressure bar of the ignition element is pressed. The reason for th

Different application ranges have different performance requirements for piezoelectric ceramic materials. 1 Perovskite piezoelectric ceramic material, the chemical formula is ABO3, A is a positive ion with a large radius, which can be +1, +2, +3; B is a positive ion with a small radius, which can be

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

Piezoelectric constant d33 of piezoelectric ceramics is a linear response coefficient that reflects the mutual coupling between the mechanical quantity (stress or strain) and the electrical quantity (electrical displacement or electric field). When a compressive stress T3 is applied along the polari
