Piezoelectric Ceramics that can use electrical and magnetic properties in the electronics industry are called electronic ceramics. Electronic ceramics finally obtain ceramics with new functions through precise control of the surface, grain boundaries and size structure. It can be widely used in energy, household appliances, automobiles, etc.
Electronic ceramic substrate materials In electronic ceramics, insulators occupy the most important position. In particular, the insulating substrate or packaging material for advanced integrated circuits can be a high-purity dense alumina sintered body with a dimensional accuracy of micrometers or less. High-purity dense alumina has insulating properties that metal materials do not have, and thermal conductivity that polymer materials do not.
Ceramic Piezoelectric Materials Piezoelectric elements can convert electrical and mechanical signals. Piezoelectric ceramic elements of a certain shape are mainly made by sintering PbTiO3-PbZrO3 system (PZT). Even if it is a sintered body, the piezoelectricity of a single crystal can be obtained by polarization. The main uses of piezoelectric components are spark plugs and resonators. The resonator acts as a radio wave filter that selectively passes a specific frequency, and is an indispensable component of a tuning circuit such as television (TV) and radio.
Ceramic semiconductor materials In ceramics, there are many semiconductors. The property of resistance changing with temperature can be used for nonlinear resistance. Negative temperature coefficient non-linear resistors (NTC non-linear resistors) decrease in resistance with increasing temperature, and have general semiconductor characteristics. Iron-based metal oxide ceramics are chemically and thermally stable, so they can be used in non-linear resistors to control temperature in a wide range. In contrast, the component called a positive temperature coefficient thermistor (PTC thermistor) uses semiconductive piezoelectric ceramics. Because this kind of ceramic has a sharp increase in resistance at the phase transition temperature, if used as a resistance heating element, it can automatically control the temperature around the phase transition temperature, which is very convenient.
Ultrasonic pressure ceramic wafer product features:
1. The impedance is lower than 2 ohms
2. Stable waveform
3. High electromechanical conversion efficiency
4. Low dielectric loss
5. Low heat
Piezoelectric ceramic materials have high electromechanical coupling coefficient, suitable dielectric constant and high sensitivity. It is mainly used for high-sensitivity transducers, flowmeter transducers, level gauge transducers, accelerometer transducers, ultrasonic detection transducers, etc.
The piezoelectric ceramic sheet material has good piezoelectricity, high mechanical strength, high coercive field, and low dielectric loss in strong fields. It is mainly used for ultrasonic cleaning, powerful ultrasonic drilling, ultrasonic welding, scaler probe, beauty instrument probe, ultrasonic scalpel probe, cardiovascular therapy instrument probe, etc.
