Electronic Ceramic Materials

Overview of electronic ceramic materials

Electronic ceramics refer to ceramic materials used in the electronics industry. They are generally used in electronic equipment as ceramic materials for installation, fixation, support, protection, insulation, isolation, and connection of various radio components and devices. They can be called insulating ceramics or device ceramics. Specific forms include circuit boards, chip packages, etc., and specific materials include oxides, nitrides, carbides, and borides. From the functional classification, the main types of electronic ceramics include insulating ceramics, dielectric ceramics, microwave ceramics, ferroelectric and piezoelectric ceramics, pyroelectric ceramics, electro-optic ceramics, electrostrictive ceramics, sensitive ceramics, high thermal conductivity ceramics, conductive ceramics, Superconducting ceramics, etc. Electronic ceramic materials belong to the cross field of fine chemicals and electronic materials.

Electronic ceramics, or ceramics for the electronics industry, are essentially different from general power ceramics in terms of chemical composition, microstructure, and electromechanical properties. These differences are formed by a series of special technical requirements put forward by the electronics industry for electronic ceramics, the most important of which are high mechanical strength, high temperature and humidity resistance, radiation resistance, and a medium constant that varies within a wide range. The tangent of 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.

The development of electronic ceramic materials is closely related to the development of physical chemistry, applied physics, silicate physical chemistry, solid state physics, optics, electricity, acoustics, radio electronics and so on. In the process, the electronic ceramics have made great progress accordingly.
