INVESTIGATION OF DUCTILE CERAMICS

Abstract

The feasibility of shaping polycrystalline aggregates of cubic ionic solids by metal forming methods, such as extrusion, was investigated. Efforts were directed toward the production of high purity, high density, fine grain-size extrusion of LiF and metallographic and electron microscope studies of the material produced. Extrusions made from powdered compact charges showed porosity, particularly at the surface. Extrusions made from high purity cast blanks produced rods showing no porosity. Although the production of polycrystalline ionic solids with ductility at room temperature was not achieved, the objective of this study does not appear unattainable. Material purity is a contributory, but not necessarily controlling factor, governing the room temperature ductility of solids.
