Silicon Nitride Nozzle and Cover Description

Silicon Nitride Nozzle and CoversSilicon nitride nozzle and cover is a man-made composite product synthesized through several different chemical reaction methods. Due to the even performance in high temperature, Si3N4 is a commonly used ceramic material 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.

The silicon nitride nozzles and covers have the characteristics of oxidation resistance, high temperature strength and less sputter adhesion, which can prolong the service life of the welding parts.

There are 5 different methods to produce silicon nitride ceramic 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.

5 star product it is

Nice product. It works flawlessly. If someone need nozzles I will just them fr this. And happy with their packing. Small parts are always delicate.

Also, they have made good packing overall.
