  • The Si3N4 composites reinforced with carbon-coated SiC whiskers were fabricated by hot-pressing at 180$0^{\circ}C$ for 2 hours to examine the effects of carbon-coated whiskers on the mechanical properties of SiC whisker reinforced Si3N4 composites. The flexural strength of the Si3N4 composites and Si3N4 monolith respectively. The weak interfacial bond between carbon-coated SiC whiskers and Si3N4 matrix which enhances the crack deflection and whisker pull-out could contribute to the improvement of mechanical properties of the composites.

  • Cordierite based glass ceramics has become an electronic substrate material for electronic circuits and the use of whickers for improving strength and toughness is evident. Pure cordierite containing 15 vol.% silicon nitride were sintered by hot-prossing and it has above 99% density. Especially, it is assumed that toughening increasing at the more high sintering temperature relevants to the glass phase increasing, as showned in the roughness of the fracture surfaces. It was directionally dependent of whisker drirection during processing.
