Abstract

Two types of silicon nitride based ceramic composites with enhanced properties have been prepared. The SiC-Si₃N₄ nano-composite with the strength of 1203 MPa, fracture toughness of 6.9 MPa · M^1/2, and Weibul modulus of 19. The fracture toughness of β-Si₃N₄ whisker reinforced Si₃N₄ composite increased from 7.2 to the 8.9 MPa · m^1/2, after coating of used whiskers by BN.
