Silicon Nitride Rod Descriptions

Silicon Nitride RodSilicon nitride rod has great strength and fracture toughness, good thermal shock resistance, and excellent wear and impact resistance. It is ideal for a wide range of applications. Its low density and great strength also enable the optimal implementation of lightweight structures.

Silicon nitride ceramic is an inorganic material ceramic that does not shrink during sintering. There are five different methods to produce Silicon Nitride including SRBSN, GPSN, HPSN, HIP-SN, and RBSN, making the application and working material different slightly.
