摘要
Glass stability and the structural role of iron oxide in xFe(2)O(3)(100 - x)[B2O3-MO] systems (M = Ca, Sr or Ba, 0 <= x <= 30 mol%) were estimated from differential thermal analysis. 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.
