Multilayered Zircon-Alumina Components Fabricated by Slip Casting

Abstract

In recent years there have been many studies attempting to increase the mechanical properties and reliability of structural ceramic materials; the forming methods used for this purpose are based on multi-layered materials to induce residual stress between interface layers. In this work were made monolithic and multi-layered materials manufactured by casting in plaster of Paris molds using zircon and alumina as raw materials, mechanical and microstructure characterizations were compared, founding that, indeed, the laminar designs can substantially improve the mechanical properties of manufactured materials by the compressive stress between the interface layers.
