Thermodynamic modelling of the structure of glasses and melts: single-component, binary and ternary systems

This paper presents the results of modelling the distribution of the basic structural units, that characterise the short-range order in various glasse s and melts, as a function of the composition and (fictive) temperature. Th e approach used is based on a purely thermodynamic model and applies equall y to binary and ternary systems, formed from components with different chem ical natures (borates, silicates, aluminosilicates, etc.), and to one-compo nent glasses (e.g., B2O3). It is shown that the model results are in good a greement with the relevant structural data available in literature. (C) 200 1 Elsevier Science B.V. All rights reserved.
