β¦ Synopsis
This paper describes the oxidation behaviour of Si 3 N 4 /Y 2 O 3 -based ceramics. We prepared three kinds of ceramics, which have excellent crackhealing abilities, in different composites -

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-
