Silicon Nitride (Si3N4)

Silicon Nitride (Si3N4) offers one of the greatest cross-sections of material properties across both oxide and non-oxide fine ceramic groups. It is a specialist solution for extreme working environments, meeting the requirements for some of the harshest industrial conditions on earth. Engineers and process managers in a range of challenging fields utilize silicon nitride ceramics to add value to their production chains, through superior mechanical and thermal performance over extended life cycles.

Silicon Nitride: Grades, Formats & Bonding Types

Silicon Nitride is a low-density fine ceramic with exceptional thermomechanical properties courtesy of its unique interlocking microstructure. Saint-Gobain produces high performance silicon nitride via hot pressing and sintering, which yields a near-net shape of outstanding strength and toughness. Hot-pressed silicon Si3N4 is usually prescribed for applications requiring the highest possible flexural strength and the maximum fracture toughness possible.

Saint-Gobain has decades of experience in the generation of high-performance technical ceramics for demanding areas of application. Our understanding of the complexities of silicon nitride ceramic formation and generation makes us one of the foremost Si3N4 ceramic suppliers worldwide
