  Abstract:  Glass stability of Fe2O3-MO-B2O3 systems (M = alkaline earth element) established from differential thermal analysis and the structural role of iron oxide in the investigated glasses are reported. The results suggest structural changes characteristic for the transition from short range to intermediate range order as the cationic field strength of the alkaline earths increases. In contrast, the iron addition has an opposite effect and determines a higher glass stability of these systems.
