Gas Pressure Sintered/GPS si3n4 ceramic ring/for bearing rollers/innovacera

In addition, its low thermal expansion coefficient gives good thermal shock resistance compared with most ceramic materials.

Silicon nitride is produced in two main ways; Reaction bonded silicon nitride (RBSN), and hot pressed silicon nitride (HPSN) and sintered silicon nitride (SSN).

RBSN is made by direct reacting compacted silicon powder with nitrogen, and produces a relatively low-density product compared with hot pressed and sintered silicon nitride, however the process has only a small volume change allowing net shape forming.

The HPSN and SSN material is made with sintering aids and offers better physical properties suitable for more demanding applications.
