低下が著しいという問題がある。Here, in Sialon or silicon nitride containing no grain boundary phase, the fracture mode is mainly intragranular fracture, so that the toughness is remarkably inferior, and the practically used sintered body is mainly a grain containing rare earth oxides. It is a composite sintered body composed of a boundary phase and sialon or silicon nitride. Therefore, the high temperature characteristics such as heat resistance of the sintered body are determined by the properties of the grain boundary phase having a lower melting point than that of sialon or silicon nitride, which is the main component. It cannot be said that the heat resistance is sufficient, and there is a problem that the strength is remarkably reduced at high temperatures.
