• How to determine whether the piezoelectric ceramic material is suitable for ultrasonic equipment?

  1. The dielectric constant should be moderateUsually the dielectric constant is 10 to 1000. If the dielectric constant is too large, it will cause direct coupling between the interdigital electrodes; if the dielectric constant is too small, the impedance will be too large and it will not be easy to

• Three polarization elements of piezoelectric ceramics

  Only under the action of the polarized electric field, the electric domains can be arranged along the direction of the electric field, so it is the main factor of the polarization condition. The higher the polarization electric field, the greater the effect of promoting the alignment of electric dom
