Silicon Nitrides (Si3N4) have a unique grain structure which delivers both exceedingly high strength and toughness and exceptionally high thermal shock resistance — making it ideal for applications with high dynamic stresses, thermal rigor, and demanding reliability requirements. Silicon nitrides also have the capacity for high-tolerance, wear-resistant finishes. This unique combination of material properties provides advantages in severe-service applications such as turbines and high-end ball bearings.
