Piezoelectric Disc Pzt Material 60*30*10 Ultrasound Ceramic Piezo Elements

Piezoelectric ceramics are a kind of electronic ceramic material with piezoelectric properties. The main difference between them and typical piezoelectric quartz crystals which do not contain ferroelectric components is that the crystal phases of the main components are all grains with ferroelectric properties. Because ceramics are polycrystalline aggregates with randomly oriented grains, the spontaneous polarization vectors of each ferroelectric grain are also disorderly oriented.

In order to make the ceramics exhibit macroscopic piezoelectric properties, it is necessary to polarize the ceramics under a strong direct current field after the ceramics are fired and coated with a compound electrode at the end face so that the polarization vectors of the original disordered orientations can choose their preferred orientations along the electric field direction. After the polarization treatment of piezoelectric ceramics, after the cancellation of the electric field, will retain a certain macroscopic residual polarization intensity, so that ceramics have certain piezoelectric properties.

Piezoelectric ceramic transducer is composed of two kinds of metal( light and weight ), and piezoelectric ceramic plates. After polarization treatment at a certain temperature, piezoelectric ceramic ultrasonic transducer will have piezoelectric effect.The piezoelectric ceramic technology has entered people's research field for a long time. The ultrasonic transducer is convenient to make with strong manipulation, high sensitivity and Good mechanical and electrical coupling.
