The effect of uni-directional orientation of SiC whisker(SiC(w)) on the pressureless sintering dens cation of SiC(w)/Si3N4 ceramics composite was investigated in relation to the content and aspect ratio of SiC(w) and the amount of sintering aids. It was found that the uni-directional orientation was effective for promoting the densification at higher SiC(w) contents. The maximum relative density obtained, however, was limited to 92 and 86% at 15 and 20vol%SiC(w), respectively.
