摘要：
Silicon nitride sintered bodies composed of fine-grained a-Si3N4 and beta'-sialon were fabricated by the gas-pressing sintering method. The silicon nitride sintered body showed a very high strength of about 2.0 GPa at room temperature, shock resistance of about 20 kJ . m(-2) (Charpy impact value) and 3-point bending fatigue limit of about 1.3 GPa.
