A STUDY OF THE PHYSICAL BASIS OF THE MECHANICAL PROPERTIES OF CERAMICS.

Abstract

A literature survey of the properties of ceram ics, both classical andrecent solid state theory, is presented. A better understanding of the ceramic properties as related to their elec tron-lattice structure was gained by correlating the mechanical properties of brittleness and duc tility with the electronic and crystalline (lat tice) properties of materials. To achieve the above, three goals were set: (1) to establish a physical basis for the brittleness and ductility of insulators (e.g., ceramics) and semi-metallic materials; (2) to develop an understanding of the role of surface energy in fracture of ceram ics and other nonmetals; and (3) to reach some practical conclusions regarding the scatter in test values for strength of ceramic specimens. Experimental methods and results are given for surface energy and Hall coefficient measurements. (Author)
