Abstract:

The report summarizes work on two areas of research. The structure of glass and The mechanical properties of glass. A comprehensive study of the structure of SiO2 by x-ray diffraction techniques indicates that silica glass is composed nearly entirely of ordered regions similar to the crystalline polymorph tridymite. Recent measurements on ion implanted silica indicate that the strength increases by as much as 50. This is the first evidence of strength increase by high energy ion stuffing.
