A network of alumina cells that remains after a vitreous silica sphere is heated in hydrogen supports the suggestion that alumina and associated sodium and lithium ions in vitreous silica are nonuniformly distributed. This distribution explains the anomalously large diffusion coefficient and electrical mobility of these alkali ions in vitreous silica.
