New Paradigm of Glass Structure and Physicochemical Essence of Glass Transition

Abstract:

The new conception of the polymeric-polymorphoid structure of glass and glassforming liquid of individual chemical substances (ICS) is presented. The analysis of numerous data of X-ray diffractometry, DSC, Raman spectroscopy etc. shows that such glassforming ICS as SiO2, GeO2. H2O, Se, GeS2, GeSe2, As2S3, AsSe, BeCl2 and other are the copolymers of the structural fragments (polymorphoids) having no translation symmetry of two (or more) polymorphous modifications (PM) of these substances. The physicochemical essence of glass transition process is discussed.
