Insulation device for electronic ceramics
In addition, high mechanical strength and chemical stability are also required.
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.
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 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.
