Silicon nitride (Si3N4)is an inorganic material technical ceramic that does not shrink during sintering. This advance ceramic has the properties of high strength, low density and high temperature resistance, especially hot-pressed silicon nitride is one of the hardest materials in the world. In addition, Si3N4 has low coefficient of thermal expansion and high thermal conductivity, so it offers excellent thermal shock resistance.
Due to the improvement of the purity of Si3N4 raw materials, the rapid development of Si3N4 powder molding technology and sintering technology, and the continuous expansion of application fields, Si3N4 is becoming an engineering structural ceramic, occupying an increasingly important position in the industry. Furthermore, Si3N4 ceramics have better mechanical properties, thermal properties and chemical stability than other high-temperature Structural Ceramics such as oxide ceramics and carbide ceramics. It is used as high-temperature structural parts in automobile engines, gas turbines and combustion chambers.
Currently, we produce variety silicon nitride ceramic nozzles in soldering appliance, silicon nitride ceramic rod,silicon nitride thermalcouple protective tube, silicon nitride ceramic heating parts in automation and gas equipment, electrical insulating ceramic parts in medical and so on.
