Microstructure of Ceramic Materials

Abstract

The properties of ceramics depend on their microstructure, which is defined by the type, size, morphology, distribution, orientation and composition of the phases present and by the interface between the grains. In the latter case, a thick or thin layer of amorphous material may be found, originating from sintering additives. The variables involved can barely be controlled in an adequate manner, which makes it difficult to predict the final properties of a porcelain with a reasonable degree of reliability.
