This book presents a comprehensive review, evaluation, and summary of the dependence of mechanical properties on grain and particle parameters of monolithic ceramics and ceramic composites. Emphasizing the critical link between fabrication and ceramic performance, the book covers the grain dependence of monolithic properties and the dependence of ceramic, composite properties on grain and particulate parameters. It includes theoretical and conceptual background, pertinent models, experimental results, a data review, discussion, and a summary or recommendations. Illustrations feature microstructural details while graphs plot data on material hardness, compressive strength, and other pivotal variables.
