Article

Glass formation and crystallization of melts in the system Na2O–K2O–CaO–MgO–Al2O–Fe2O3–SiO2–MnO2 with different Fe2O3 content are studied. A mechanism is proposed for the crystallization of glass from the standpoint of the acid-base concept of silicate melts. The role of aluminum and iron ions as glass formers of the elemental-oxygen framework or as modifiers as a result of the displacement of acid-base equilibria with a change of the iron oxide content is shown.

Key words

acid-base concept silicate melt glass formation crystalline phase
