Effects of nitrogen and carbon ion implantation on devitrification of silica glasses

摘要: Abstract The effects of nitrogen and carbon ion implantation on devitrification stoichiometric oxygen deficient silica glasses were investigated. Linear crystal growth was observed in glass not affected by implantation. Parabolic oxygen-deficient glasses, which retarded implantation, with the rate retardation being greater for than Activation energy parabolic constant about ∼ 105 kcal/mol. When hydrated, their became linear activation energies smaller. reduction hydration approximately equal to water diffusion silica. It is suggested that decreased forming an oxynitride layer, effective barrier.
