  Let me explain to you about the types of electronic ceramics

  Electronic ceramics is a new type of ceramic material with unique electrical, optical, magnetic and other properties. It is an optoelectronic industry and a high-tech new material with fierce international competition.

                                                      Electronic Ceramics

  Classification of electronic ceramic materials

  Electronic ceramics can be classified into insulating device ceramics, ferroelectric ceramics, semiconductor ceramics, and high-speed ion ceramics according to their functions and uses.

  Insulation device porcelain Insulation device porcelain has excellent electrical insulation properties and is used for electronic ceramics such as structures, substrates and casings in electronic equipment and devices. Insulation device porcelain includes various insulators, electronic tube brackets, capacitor support brackets, integrated circuit substrates, Outer shell, etc.

  Capacitor ceramics refer to electronic ceramics used as capacitor dielectrics, and there are many specifications and varieties, mainly including high-frequency and low-frequency capacitor ceramics and semiconductor capacitor ceramics. They are mainly used to manufacture ceramic capacitors and temperature compensation capacitors with high stability in high-frequency circuits. The main components of this ceramic are mostly solid solutions based on titanates and titanates of alkaline earth metals or rare earth metals.

  Ferroelectric/Piezoelectric Ceramics

Ferroelectric ceramics are electronic ceramics  with ferroelectric crystals as the main crystal phase . There are more than a thousand ferroelectric crystals that have been discovered, but the main crystal phase of ferroelectric ceramics is mainly perovskite or quasi-perovskite iron. Transistor or solid solution, within a certain temperature range, there is a spontaneous polarization that can be switched by applying an electric field. Ferroelectric ceramics have many functions and are widely used, and piezoelectric devices can be manufactured by using their piezoelectric properties. This is the core of ferroelectric ceramics. The main application, so ferroelectric ceramics are often called piezoelectric ceramics.

  Semiconducting Ceramics

  Semiconductor ceramics refer to polycrystalline ceramic materials formed by ceramic technology. Unlike single crystal semiconductors, there are many grain boundaries, and the semiconductorization of grains is also carried out during the sintering process. Semiconductor ceramics are heat sensitive, humidity sensitive, Gas-sensitive, pressure-sensitive, and photosensitive resistors are various. In addition to single-phase ceramics composed of one compound such as oxide ceramics, nitride ceramics, and carbide ceramics, semiconductor ceramics also have composite ceramics composed of two or more compounds. , thermistor elements are widely used in industrial electronic equipment and home appliances, among which positive temperature coefficient thermistor material (PTC) ceramics are widely used in a wide range of applications. Self-controlled heating element.

  Speed ​​Ion Ceramics Speed ​​Ion Ceramics

  Instant ion-conducting electronic ceramics , which have the characteristics of rapidly transmitting positive ions, and its representative is -Al2O3, which has many uses different from electron conductors, for example, applications in solid-state electronic devices and separator materials for various batteries Among them, normal temperature primary batteries, fuel cells, storage batteries, coulometers, gas sensors, variable resistors, electrical integrators, electric double layer capacitors, etc. have been put into practical use.
