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 dimensional 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, for insulating substrates or packaging materials for advanced integrated circuits, high-purity dense alumina sintered bodies with a dimensional accuracy of micrometers or less can be used. 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 signals and mechanical signals to each other. 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 non-linear resistance. Negative temperature coefficient nonlinear resistors (NTC nonlinear resistors) decrease in resistance as the temperature rises, and have general semiconductor characteristics. Iron-based metal oxide ceramics are chemically and thermally stable, so they can be used for non-linear resistors to control the temperature in a wide range. On the contrary, the component called PTC thermistor (PTC thermistor) uses semiconductorized BaTiO3 ceramics. This kind of ceramic has a sharp increase in resistance at the phase transition temperature. If it is used as a resistance heating element, it can automatically control the temperature around the phase transition temperature, which is very convenient.

In order to improve the reliability of piezoelectric ceramics, we usually use metal shell packaging to reduce the lateral force that external mechanical structures may bring to piezoelectric ceramics. However, even if piezoelectric actuators that use shell packaging are used, it is necessary to go deeper Understand the technical background of piezoelectric ceramic applications, and ensure high reliability through appropriate design and operation.
Even if the structure of the piezoelectric system has proven to be reliable, any seemingly minor changes need to be re-evaluated. In some practical applications, the reliability of piezoelectric ceramics is often discussed under the following two extreme conditions.
Every link in the operation process must be strictly controlled, through actual testing and evaluation procedures, to avoid overloading, unreasonable mechanical structure, mechanical compensation and correction of inappropriate driving conditions, so as to achieve high reliability.
Piezoelectric ceramics can output performance based on limited parameters in a short time, but we would not recommend this method. When long-term reliability, long-term work and high duty cycles are necessary conditions, the successful short-term test of a piezoelectric system does not mean that it is equally safe and reliable for long-term use. Incorrect operation will not immediately damage the piezoelectric ceramics, but will reduce long-term reliability and fail to achieve the expected working cycle.

PiezoelectricCeramics (PZT) materials are categorized as functional ceramics. In sensors they make it possible toconvert forces, pressures and accelerations into electrical signals, and in sonic and ultrasonic transducers and actuators they convert electric voltages into vibrations or deformations.PiezoelectricCeramics materials are classified according to their chemical composition on the one hand, and by the specific application conditions on the other.
