What Are Piezoelectric Ceramics?
  • Industrial piezoelectric ceramic plate are an important electronic material with unique physical properties and a wide range of application scenarios. Piezoelectric ceramic sheets are electronic ceramic materials with piezoelectric effects. When this material is subjected to external pressure, it generates charges inside, forming an electric field, and thus generating voltage. Meanwhile, when a voltage is applied, the material undergoes corresponding deformation, which is the unique feature of piezoelectric ceramics.

    Industrial piezoelectric ceramic sheets have advantages such as high sensitivity, high resolution, and low hysteresis. It can work in extreme environments such as high temperature, low temperature, and high vacuum, and has long-term stability and reliability. In addition, industrial piezoelectric ceramic sheets can also be processed and prepared through different process technologies, such as thin film preparation, thick film preparation, multi-layer structure preparation, etc.

    History of Piezoelectric Ceramic

    1880, The Curie brothers first discovered the piezoelectric effect of tourmaline, marking the beginning of the history of piezoelectricity.

    1881, The Curie brothers experiment verified the inverse piezoelectric effect and provided quartz with the same positive and negative piezoelectric constants.

    1894, Voigt pointed out that only crystals with twenty different point groups without symmetric centers are likely to have piezoelectric effects, and quartz is a representative of piezoelectric crystals that have been applied.

  • Applications of Piezoelectric Ceramics

    Piezoelectric manufacturers like us provide various types of piezoeletric ceramics for dfferent market sectors.

    Some of our Piezoelectric ceramic applications include:

    Medical - Bone conduction hearing aids, Ultrasonic surgical instruments, Micro and nano-dosing equipment

    Communications - Antennas, Sensors

    Optics - Fiber positioning, turntable lasers

    Automotive - Knock sensors, Fuel injectors

    Commercial - Alarms, Buzzers, Printers

    Piezoelectric ceramics are a type of electronic ceramic materials with piezoelectric properties. The main difference from typical piezoelectric quartz crystals that do not contain ferroelectric components is that the crystal phases that make up their main components are grains with ferroelectricity. Due to the fact that ceramics are polycrystalline aggregates with randomly oriented grains, the spontaneous polarization vectors of each ferroelectric grain are also randomly oriented. In order for ceramics to exhibit macroscopic piezoelectric properties, it is necessary to place them under a strong DC electric field for polarization treatment after being fired and coated with composite electrodes on the end face of the piezoelectric ceramics, in order to make the polarization vectors of the original chaotic orientation preferentially oriented along the direction of the electric field. After polarization treatment, piezo electric ceramics retain a certain macroscopic residual polarization strength after the electric field is cancelled, thus giving the ceramics certain piezoelectric properties.

    Industrial piezoelectric ceramic sheets have wide applications in many fields, such as medical imaging technology, audio and ultrasound equipment, precision measurement instruments, military radar, and sonar systems. Among them, medical imaging technology is one of the important application fields of industrial piezoelectric ceramic sheets, which can be used for medical diagnosis and treatment. In addition, industrial piezoelectric ceramic sheets can also be used to manufacture precision components such as high-frequency transducers, ultrasonic sensors, and optical modulators with micrometer level accuracy.

    With the continuous development of technology, the application prospects of industrial piezoelectric ceramic sheets are becoming increasingly broad. In the future, industrial piezoelectric ceramic sheets will develop towards high-frequency, high-precision, miniaturization, and integration. Meanwhile, with the continuous emergence of new materials and technologies, the performance and reliability of industrial piezoelectric ceramic sheets will also be further improved. In addition, with the continuous improvement of environmental awareness, the production and use of industrial piezoelectric ceramic sheets will also pay more attention to environmental protection and sustainable development.

    Industrial piezoelectric ceramic sheets are an electronic material with important application value. Their unique physical properties and wide application scenarios make them an indispensable part of modern industrial and medical fields. In the future, with the continuous development of technology, the application prospects of industrial piezoelectric ceramic sheets will be even broader.
