i3-Sialon ceramics were prepared by reactive hot pressing sintering method with a一Si3 NQ,a-AlZ 03,and sintering additive Mg0 as raw materials. Effect of sintering additive Mg0 and the sintering temperature on me-G’han1G’al property an(1 morphology Were SystematlG’ally studle(l.

Along with the sintering tempera-ture increasing,the bending strength and the fracture toughness of月一Sialon ceramics increased before they are low-er. At the sintering temperature of 1 600℃,the preparation of月一Sialon ceramics obtained the highest bendingstrength and fracture toughness,the value ( 423 MPa,2. 73 MPa·mvzm),combined closely. The principal fracture
