35x15x5mm Piezoelectric Element Piezo Ceramic Ring

Piezoelectric ceramics are a class of electronic ceramic materials with piezoelectric properties. The main difference from typical piezoelectric quartz crystals that do not contain ferroelectric components is that the crystal phases that make up their main components are ferroelectric crystal grains. Since the ceramic is a polycrystalline aggregate in which the crystal grains are randomly oriented, the spontaneous polarization vector of each ferroelectric crystal grain is also chaotically oriented. In order for the ceramic to exhibit macroscopic piezoelectric characteristics, it is necessary to fire in the piezoelectric ceramic. After the end face is double-electrode, it is subjected to polarization treatment under a strong direct current electric field, so that the respective polarization vectors of the original chaotic orientation are preferentially oriented along the direction of the electric field. The piezoelectric ceramic after polarization treatment is in the electric field. After the cancellation, a certain macroscopic remnant polarization is retained, so that the ceramic has a certain piezoelectric property. 35x15x5mm Piezoelectric Element Piezo Ceramic Ring
