• Performance test method of piezoelectric ceramic material

  Curie temperatureWhen the temperature is higher than the curie temperature (Tc), the piezoelectric ceramic is in the paraelectric phase, and the spontaneous polarization and piezoelectricity also disappear. At the Curie temperature, many physical properties of piezoelectric ceramic materials, such a

• 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

• What is a piezo buzzer used for ?

  A buzzer or beeper is an audio signalling device,[1] which may be mechanical, electromechanical, or piezoelectric (piezo for short). Typical uses of buzzers and beepers include alarm devices, timers, and confirmation of user input such as a mouse click or keystroke.Piezoelectric HistoryPiezoelectri

• Electroacoustic component - piezoelectric ceramic pronunciation chip

  Piezo sounder ceramic element is a piezoelectric ceramic that can vibrate and sing under the excitation of an alternating electric field after being bonded to a metal substrate. However, because the acoustic impedance of the air does not match, the sound emitted is very small; the high-decibel buzze

• Single-side ground alumina piezo ceramic substrate

  By adding a rust inhibitor, the alumina piezo ceramic substrate can be effectively prevented from becoming yellowish after polishing, and the polishing effect is not affected. Therefore, in the high-efficiency thinning and ultra-smooth polishing of alumina piezo ceramic substrates, it is possible to
