Abstract
Silicon nitride sintered bodies are disclosed herein which each contain an intergranular phase. The intergranular phase contained in the sintered body is crystallized into diopside structure type crystals and apatite structure type crystals. The silicon nitride sintered bodies have excellent density and mechanical strength as well as extremely excellent static fatigue characteristics, and therefore are applicable as various mechanical structural parts such as engine parts, gas turbine parts, etc.
