Abstract

Silica (SiO₂) nano-layer was coated on silicon carbide (SiC) powder by rotary chemical vapor deposition (RCVD). The SiC/SiO₂ composite were consolidated by spark plasma sintering (SPS) at 1923 K using the SiO₂ coated SiC powder. The relative density and hardness of the SiC/SiO₂ composites increased with increasing SiO₂ content, and were 97% and 17 GPa, respectively, at SiO₂ content of 22 mass%. The relative density and hardness of a composite consolidated using the mixture powders of SiC and SiO₂ (22 mass%) at 1923 K were 81% and 8 GPa, respectively.
