Piezoelectric ceramic is a functional pzt ceramic material which can transform mechanical energy and electrical energy. The so-called piezoelectric effect refers to the positive piezoelectric effect that when some media are under mechanical pressure, even if the pressure is as small as the sound wav

Voice converter is one of the most common applications. Piezoelectric ceramics can be used as ultrasonic sound transducers such as pickups, microphones, headphones, buzzers, ultrasonic sounders, sonar, and ultrasonic flaw detectors of materials. For example, a buzzer on a children ’s toy is a curre

Parameters of piezoelectric materials and piezoelectric equations (3)(11)Mechanical quality factor QmWhen the PZT material piezo ceramic is used for resonance vibration, it is necessary to overcome the internal mechanical friction loss (internal consumption), and when there is a load, it is necessar

Mine inclination measurement is a new technology for mine borehole measurement, and it is an important means for comprehensive advance detection and structural positioning. Due to its unique role in pre-exploration exploration of piezo ceramic tubes, a number of corresponding technical studies have

Since the curie brothers discovered the piezoelectric effect of tourmaline in 1880, piezoelectric science has officially entered the stage of human science and technology civilization. Early theoretical research was mainly done by the curie brothers later. In 1881, the curie brothers verified the in

There are many methods for forming ceramic embryo , such as pressure forming, plastic forming and slurry forming. Each type of forming method can be divided into several specific forming methods of Pzt ceramic disc. It can be selected according to the shape, specification and size of the product, bu
