Si 3 N 4 /SiC composite ceramics were sintered in order to investigate their bending strength behavior after crack-healing. Y 2 O 3 and TiO 2 powder was added as sintering additives to enhance it's sintering property. A three-point bending specimen was cut out from sintered plates. About 100 m semi-
