Crystallization of annealed Li/sub 2/O.2SiO/sub 2/ glasses implanted with inert ions and fused SiO/sub 2/ glass implanted with Li ions was monitored using infrared reflection spectroscopy. Elastic recoil detection analysis was used to study changes in the Li and H concentration induced in these glasses by implantation and annealing. Implantation of Li/sub 2/O.2SiO/sub 2/ with inert ions results in Li depletion, accompanied by H indiffusion, in the implanted region. For Li-implanted SiO/sub 2/, crystallization of ..cap alpha..-quartz is accompanied by appreciable Li diffusion to the surface and attendant H migration to the Li-depleted region. The crystallization mechanisms are discussed in terms of phase separation in the lithia-silica system.
