Silicon Nitride Seals
Hot pressed silicone nitride seals from Saint-Gobain provide outstanding fracture resistance and toughness for nuclear and other high-temperature applications
Hot pressed silicon nitride (Si3N4) offers increased strength at higher temperatures and remains thermodynamically stable due to its low thermal expansion coefficient.
That’s why Noralide® NBD-200 hot pressed silicon nitride (Si3N4) from Saint-Gobain makes an ideal material for seal face components in nuclear applications. Hot pressed for maximum strength and density, Noralide® Si3N4 provides better fracture resistance than other ceramic or metal refractory materials.
In addition to its high hardness, as well as excellent creep and wear resistance properties, Noralide® seal face components are lighter weight with exceptional shaping capabilities.
