Silicon Nitride Rod Description:

Silicon Nitride Rod is a commonly used ceramic material in the metallurgical industry due to the even performance in high temperature. Silicon Nitride Rod 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 Welding Rod 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 Silicon Nitride components.

Silicon Nitride Rod Applications:

Silicon Nitride Rod can make products including:

- Advanced ceramic tubes
- Bearing rollers
- Ceramic cutting materials
- Cyrol bearing rollers
