Description:
Dense AlN–SiC solid solution ceramics with 25–75 mol% AlN were fabricated by spark plasma sintering using hexagonal SiC and AlN powders without additives. The bending strength reaches 800 MPa at room temperature with a fracture toughness of about 5 MPa·m 1/2 . The high bending strength can be retained at high temperatures, maintaining over 400 MPa at 1700°C.
