Top Seven Trends In Piezoelectric Ceramics To Watch
Piezoelectric ceramic as a transducer, the scope of its application is broader than the oscillator. driving a piezoelectric transducer are one of them. They are underwater acoustic devices that emit and receive ultrasound underwater device.
They are also widely used in industries as ultrasonic cleaning, ultrasonic precision machining, ultrasonic humidification and ultrasonic diagnostics.
Circuit of transducer piezoelectric crystal is widely used area for today's piezo-ultrasonic transducers is telemetry and remote control systems such as remote-controlled TV channel switching systems, automatic control of parking time recorders, and more.
The specific application examples are: piezoelectric ceramic buzzer, piezoelectric ignition, ultrasonic microscope, etc. PZT-4 piezo ceramics have been widely used. In the electronics industry to use electricity, magnetic ceramics, called electronic ceramics.
Electronic PZT-5 piezo ceramics are the ultimate in ceramic with new functions through the precise control of the surface, grain boundaries and size structures. In the energy, household appliances, cars, etc. can be widely used.Electronic ceramic substrate material In electronic ceramics, occupy the most important position is the insulator.
In particular, piezo ring for flow measurement is an insulating substrate or an encapsulating material for a high-level integrated circuit, a high-purity dense alumina sintered body having a dimensional accuracy of micrometers or less can be used. High-purity dense alumina metal materials do not have the insulation and polymer materials do not have the thermal conductivity.
Piezoelectric ceramic piezoelectric materials can make the electrical signal and the mechanical signal conversion. Piezoelectric ceramic elements of a certain shape are mainly produced by sintering a PbTiO3-PbZrO3 system (PZT), and even if it is a sintered body, the piezoelectric property of the single crystal can be obtained by polarization. The main uses of piezoelectric components are spark plugs and resonators.
Resonators piezo rings transducer pzt 8 through filters of specific frequency and are indispensable components for tuning circuits such as TVs and radios.
