Abstract

Abstract

α-SiC ceramic was obtained by hot-pressing of α-SiC powders with B and C as additives. The relative density of the materials is 97.8%, which was hot-pressed at 1900℃ and 25 MPa. The values of the flexural strength and fracture toughness reached 383 MPa and 4.95 MPa·m^1/2 respectively.The densification mechanism was deduced.
- silicon carbide,
- hot-pressing,
- solid state sintering
