Silicon Nitride Ceramic:
Electronic ceramics refer to ceramics that can utilize electrical and magnetic properties in the electronics industry. Electronic ceramics finally obtain ceramics with new functions through precise control of the surface, grain boundaries and size structure. It can be widely used in energy, household appliances, automobiles, etc. Many sintered body materials mainly composed of oxides are widely used in the production of electronic functional components. The manufacturing process of electronic ceramics is roughly the same as that of traditional ceramics. Electronic ceramics, or ceramics for the electronics industry, are fundamentally different from general ceramics for electric power 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 is to have high mechanical strength, high temperature and humidity resistance, radiation resistance, and a wide range of dielectric constants. The dielectric loss tangent value is small, and the capacitance temperature coefficient can be adjusted (or the capacitance change rate can be adjusted). High electrical strength and insulation resistance, and excellent aging performance. 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, etc., and they promote each other, thus making a leap in the development of electronic technology. China has made great progress in electronic ceramics accordingly.
properties:
High hardness, high strength, wear resistance, corrosion resistance, high temperature(1200°), good thermal diffusivity, good thermal shock resistance(avoid the temperature changing rapidly), good insulativity, low density. The comprehensive properties are best in most of structure ceramic.
