Silicon nitride ceramic, also known as Si3N4 ceramic, is an inorganic material that does not shrink when the ceramic is sintered. It is very strong, especially hot-pressed silicon nitride, which is one of the hardest substances in the world. It has high strength, low density, high temperature resistance and other properties. The basic structural unit of Si3N4 ceramics is [SiN4] tetrahedron, which forms a continuous and firm network structure in three-dimensional space.
Silicon nitride ceramic is a multifunctional material with good mechanical properties, heat resistance, corrosion resistance, wear resistance, chemical resistance, electrical conductivity and thermal stability. Therefore, silicon nitride ceramics are widely used in many fields, mainly in the following aspects.
The electronics industry is one of the major industries using silicon nitride ceramics. It can be used to manufacture electronic components, such as capacitors, inductors, resistors, etc. It has the characteristics of high precision, high reliability, high withstand voltage, etc., and can meet the high requirements of the electronics industry.
The chemical industry is another industry that uses silicon nitride ceramics. It can be used to manufacture chemical instruments and equipment, such as heat exchangers, valves, pipes, storage tanks, etc. It has good corrosion resistance and can effectively handle various corrosive liquids.
The mechanical industry is another field that benefits from the use of silicon nitride ceramics. It can be used to manufacture mechanical parts, such as bearings, bushings, bushings, bushings, etc. It has good mechanical strength and wear resistance, and can meet the high requirements of the machinery industry.
