This book discusses the synthesis, performance and applications of ceramic materials. Chapter One presents the recycling of biomass ashes in the obtaining of clay bricks for possible use as construction material. Chapter Two summarizes the use of nanostructured ceramics for the control of heat flows. Chapter Three deals with analytical modelling of thermal stresses in a multi-particle-matrix system with isotropic cylindrical particles which are periodically distributed in an isotropic infinite matrix. Chapter Four deals with analytical modelling of thermal stresses which originate during a cooling process of an elastic solid continuum. Chapter Five provides recent information on the use of zirconia in dentistry, its characteristics and indications, with a particular emphasis on surface conditioning methods to promote adhesion of resin-based materials to zirconia.
