| Abstract: | In this paper the effect of cristobalite content on properties in silicon carbide material with oxide binding is studied. The results show that the cristobalite formed from silica causes strength decrease, but appropriate cristobalite content is benificial to material toughness. The strength and toughness can be partly improved by controling silica content. |
