Silicon nitride plate is a man-made compound synthesized through several different chemical reaction methods. Due to the even performance in high temperature, silicon nitride plate is a commonly used in the metallurgical industry. It has excellent thermal shock resistance due to the microstructure. The creep and oxidation resistance of Si3N4 is also superior, its low thermal conductivity and high wear resistance also make it an outstanding material that can withstand conditions of most industrial applications.
There are 5 different methods to produce Silicon Nitride including SRBSN, GPSN, HPSN, HIP-SN and RBSN, make the application and working material different slightly. In these 5 methods of production, GPSN is most commonly used to produce Si3N4 components.
* High strength over a wide temperature range
* High fracture toughness
* High hardness
* Outstanding wear resistance, both impingement and frictional modes
* Good thermal shock resistance
* Good chemical resistance
