Si 3 N 4 -O'SiAlON composites using waste-Si-sludge was fabricated by gas-pressure-sintering (GPS) process at 1950°C for 3.5 h. The percent nitridation of waste Si compacts showed a lower value than that of using commercial Si powders caused by the high contents of oxygen in the waste Si particles. Some amounts of Si 2 N 2 O and Y 2 Si 2 O 7 phases were also detected in the reaction-bonded Si 3 N 4 (RBSN) although main components were α-Si 3 N 4 , β-Si 3 N 4 and residual Si phases. In the post-sintered body by GPS, no residual Si, α-Si 3 N 4 , Si 2 N 2 O and Y 2 Si 2 O 7 phases were detected except the β-Si 3 N 4 and O'SiAlON. The grain growth of rod-like Si 3 N 4 grains was inhibited by the dispersion of fine O'-SiAlON particles. The fracture toughness and strength of Si 3 N 4 -O'SiAlON composites were 5.6 MPa.m 1/2 and 456 MPa, respectively.
