320KHZ PZT-4/pzt-8 Piezo Ceramic Disk Ultrasonic Distance Sensor
PZT piezoelectric ceramic chip: scientific name: lead zirconate titanate, abbreviated PZT in English, where p is the abbreviation of lead element Pb, Z is the abbreviation of zirconium element Zr, and t is the abbreviation of titanium element ti. PZT piezoelectric ceramics are polycrystalline sintered from lead dioxide, lead zirconate and lead titanate at 1200 ℃. It has positive piezoelectric effect and negative electric effect.
Piezoelectric ceramic buzzer is mainly composed of piezoelectric ceramic and metal substrate. Substrate materials generally include iron, copper, steel, nickel alloy sheet. Different substrates are selected according to the acceptable price and performance required by customers. Piezoelectric ceramic sheet belongs to the category of ferroelectrics, which is a kind of Artificial Polycrystalline piezoelectric material. It has a domain structure similar to that of ferromagnetic material.
