About Electronic Ceramics Introduction

About Electronic Ceramics Introduction

Electronic ceramics refer to ceramics that can utilize electrical and magnetic properties in the electronics industry. Electronic ceramics are ceramics with new functions that are finally obtained through precise control of the surface, grain boundaries and dimensional structure. It can be widely used in energy, household appliances, automobiles, etc.

Electronic Ceramics | Semiconductor Ceramics

Electronic ceramics with semiconducting grains and insulating (or semiconducting) grain boundaries through semiconducting measures, thereby exhibiting strong interface barriers and other semiconducting properties.

There are two main methods of ceramic semiconductorization: forced reduction method and donor doping method (also known as atomic valence control method). Both methods create defects such as ionic vacancies in the crystal of the ceramic, which provide a large number of conducting electrons, making the grains in the ceramic a certain type (usually N-type) semiconductor. And the interlayer between these grains is an insulating layer or another type (P-type) semiconductor layer.

Electronic Ceramics | Capacitor Ceramics

Electronic ceramics are electronic ceramics used as capacitor dielectrics. This type of ceramics has the largest amount and the largest variety of specifications. The main ones are high frequency, low frequency capacitor porcelain and semiconductor capacitor porcelain.

  • High-frequency capacitor porcelain belongs to Class I capacitor porcelain, which is mainly used to manufacture high-stability ceramic capacitors and temperature compensation capacitors in high-frequency circuits.
  • Low-frequency capacitor porcelain belongs to Class II capacitor porcelain, which is mainly used to manufacture ceramic capacitors for bypass, DC blocking and filtering in low-frequency circuits. 
  • Semiconductor capacitor ceramics Electronic ceramics that use the insulating layer formed on the outer surface of the semiconducting ceramic or the inner surface (grain boundary) between the grains as the capacitor medium.

Electronic Ceramics | Insulation Device Porcelain

Insulation device for electronic ceramics

  • Excellent electrical insulation properties, used as electronic ceramics for structural parts, substrates and casings in electronic equipment and devices.
  • Porcelain parts of insulating devices include various insulators, coil bobbins, electronic tube sockets, band switches, capacitor strut brackets, integrated circuit substrates and packaging shells.

In addition, high mechanical strength and chemical stability are also required.

Advantages of Electronic Ceramics

Electronic ceramics or ceramics for electronic industry are essentially different from general power ceramics in chemical composition, microstructure and electromechanical properties. These differences are formed by a series of special technical requirements put forward by the electronic industry for electronic ceramics, the most important of which are high mechanical strength, high temperature and humidity resistance, radiation resistance, and dielectric constant changes in a wide range. The tangent value of the dielectric loss angle is small, and the temperature coefficient of capacitance can be adjusted (or the rate of change of capacitance can be adjusted). High electrical strength and insulation resistance, and excellent aging properties.
