Demanding aerospace applications challenge the performance limits of conventional materials. Ceralloy® Silicon Nitride is an excellent material solution based on its high temperature strength, excellent fracture toughness, high hardness and tribological properties. Silicon nitride aerospace applications result in superior mechanical reliability and wear resistance.





Ceralloy® Silicon Nitride is produced using patented compositions and processing techniques that result in an in-situ silicon nitride interlocking needle-like microstructure. This microstructure toughens the silicon nitride by a crack-deflection process similar to that found in composite materials. The result is a monolithic silicon nitride that has exceptional hardness and superb fracture toughness.
