PZT-8/PZT-4 Material Piezoelectric Ceramic Disc For Ultrasound

1、  Piezoelectric ceramic Application of special sensitive ceramic sensor in automobile

It is required that the electronic ceramic sensor used in automobile can be used for a long time in the harsh environment (high temperature, low temperature, vibration, acceleration, humidity, etc.). It should have the characteristics of small size, light weight, good reusability and wide output range. In recent years, with the progress of manufacturing technology, ceramic has been fully utilized for its heat resistance, corrosion resistance, wear resistance and potential excellent electromagnetic and optical functions.

 

 

2、  Piezoelectric ceramic Application of ceramic materials in automobile spraying technology

In recent years, aerospace technology has been widely used, and ceramic film spraying technology has been applied to automobiles. This technology has the advantages of good thermal effect, high temperature and high pressure, mature process and stable quality. In order to achieve the goal of low heat dissipation, ceramic spraying can be carried out on engine combustion chamber components, such as zirconia sprayed on piston top and zirconia sprayed on cylinder liner. After this treatment, the engine can reduce the heat loss, reduce the weight of the engine itself, reduce the size of the engine, and reduce the fuel consumption.

 

 

 

3、  Piezoelectric ceramic Application of alumina ceramic shock absorber

Intelligent shock absorber is successfully developed by using the positive piezoelectric effect of sensitive ceramics and the converse piezoelectric effect and electrostrictive effect of alumina ceramics. Due to the use of high-sensitivity ceramic components, the shock absorber has the function of identifying road surface and self-adjusting, which can minimize the vibration caused by rough road surface.
