Silicon Nitride Welding Rod Description
Silicon Nitride Welding Rod is a commonly used ceramic material in the metallurgical industry due to its even performance at high temperatures. Silicon Nitride Welding 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 Rods including SRBSN, GPSN, HPSN, HIP-SN, and RBSN, making the application and working material different slightly. In these 5 methods of production, GPSN is most commonly used to produce Silicon Nitride components.
