Piezoelectric ceramics is a kind of information functional ceramic material that can convert mechanical energy and electrical energy-piezoelectric effect. In addition to piezoelectricity, piezoelectric ceramics also have dielectric properties, elasticity, etc., and have been widely used in medical imaging, Acoustic sensors, acoustic transducers, ultrasonic motors, etc. Piezoelectric ceramics are made by using their materials to cause relative displacement of the positive and negative charge centers inside the material under the action of mechanical stress, resulting in polarization, which leads to the occurrence of bound charges with opposite signs on both ends of the material, that is, the piezoelectric effect. It has sensitive characteristics. Ceramics are mainly used to manufacture ultrasonic transducers, underwater acoustic transducers, electroacoustic transducers, ceramic filters, ceramic transformers, ceramic discriminators, high voltage generators, infrared detectors, surface acoustic wave devices, electro-optical devices, And piezoelectric gyroscopes, in addition to being used in high-tech fields, it is more to serve people in daily life and work hard to create a better life for people.

Electronic ceramics 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.

The development of electronic ceramic materials is closely related to the development of physical chemistry, applied physics, silicate physical chemistry, solid-state physics, optics, electricity, acoustics, and radio electronics. In China, electronic ceramics have also made great progress accordingly.

Electronic ceramics can be divided into five categories according to their functions and uses: insulating ceramics, capacitor ceramics, ferroelectric ceramics, semiconductor ceramics and ion ceramics.

Application of special sensitive ceramic automotive sensors
Electronic ceramic sensors for automobiles are required to be suitable for a long time in the harsh environment of automobiles (high temperature, low temperature, vibration, acceleration, humidity, sound, exhaust gas), and should have the characteristics of small and light weight, good reusability, and wide output range. Ceramic heat-resistance, corrosion-resistance, wear-resistance and its potential excellent electromagnetic and optical functions have been fully utilized in recent years with the advancement of manufacturing technology. Sensors made of sensitive ceramic materials can fully meet the above requirements.

Application of ceramic materials in automobile spraying technology
In recent years, aerospace technology has been widely used in ceramic film spraying technology and began to be applied to automobiles. The advantages of this technology are good thermal effect, can withstand high temperature and pressure, mature technology, and stable quality. In order to achieve the goal of low heat dissipation, ceramic spraying can be applied to the engine combustion chamber components, such as zirconia spray on the top of the piston and zirconia spray on the cylinder liner. After this treatment, the engine can reduce heat loss, reduce the quality of the engine itself, reduce the size of the engine, and reduce fuel consumption.

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.

Application of Alumina Ceramic Automobile Shock Absorber
The high-end car vibration damping device has successfully developed an intelligent shock absorber by comprehensively using the positive piezoelectric effect of sensitive ceramics and the electrostrictive effect of the inverse piezoelectric effect of alumina ceramics. Due to the use of high-sensitivity ceramic components, this type of shock absorber has the function of identifying the road surface and can do self-adjustment, which can minimize the vibration of the car due to the rough road surface.
