Abstract
The Si3N4 ceramic reinforced with 30 wt% 3YZrO2(ZrO2 containing 3 mol%Y2O3 has been fabricated by two kinds of processes (hot press and presureless sintering). The ZrO2/Si3N4 composites exhibited a high fracture toughness and flexural strength, and lower thermal conductivity than Si3N4 matrix material. The ZrO2/Si3N4 composite is suggested to be a very hopeful candidate material as component of heat engine applications. In this paper, the microstructure and phase composition of the composites are studied by SEM and XRD. The toughening mechanism of ZrO2 in the ZrO2/Si3N4 composites is discussed.
