Abstract
A model is described for the densification of ceramics and particle-reinforced ceramic-matrix composites when the degree of shrinkage is large. A rule of mixtures model can be used to describe the degree of densification in cases where there is no interfacial reaction between the reinforcement and the matrix. These models are illustrated by the reaction sintering of sialon and of sialon with titanium nitride, and also by the sintering of clay containing silicon carbide. The extent of linear shrinkage and also the rate of densification decrease with increasing volume fraction of reinforcement and these effects are explained on the basis of the model. The correspondence between the data and the model allow the prediction of shrinkage in particle-reinforced composite systems where there is no interfacial reaction during the densification process.
