Abstract
A qualitative working model is presented in this paper for the development of tough ceramics. The model shows that toughness can be imparted only to dispersed multiphase ceramics in preference to single phase ceramics. A simultaneous improvement in strength can be achieved by securing a strong bond between the dispersed phase and the matrix. Eutectic composites of mixed oxides merit serious consideration as potential tough ceramics.
