Abstract
AbstractOn the basis of the concept of polymer–polymorphoid structure of glass and glass‐forming liquid the experimental data are analyzed which are connected with structural and relaxation processes in condensed SiO2. It is shown that all relaxation processes in liquid and vitreous silica have a uniform physical‐chemical nature – interconversion of structure fragments (polymorphoids) of the various crystal polymorphic modifications that do not have translational symmetry (long‐range order), copolymerized to a greater or lesser extent, accordingly, in vitreous or liquid state.
