Arnold, G W

Controlled crystallization of glass through ion-implantation technology provides a means of altering near-surface physical properties, e.g., composition, hardness, reactivity, and refractive index. These changes may be desirable from the standpoint of electro- optical device fabrication technology. We have achieved crystallization through ion-implantation and appropriate thermal annealing. Three approaches have been used: (1) catalyzed precipitation of the crystalline phase on colloidal implanted metal (Au, Ag) in a lithia-alumina-silica (LAS) glass, (2) crystalline quartz growth on Li-implanted fused silica, and (3) crystallization of Li{sub 2}O{lg bullet}2SiO{sub 2} glass by inertgas ion implantation. The processing methods and our understanding of the phenomenology are discussed in detail. 16 refs., 16 figs.
