摘要：

Two vitreous systems, xFe(2)O(3) (.) (1-x)[3B(2)O(3)(.)MO] (MOdouble right arrowCaO or CaF2) with 0less than or equal toxless than or equal to0.5 were prepared and characterized by IR spectroscopy. It was established the mode in which both Fe2O3 and the partial replacing of the oxygen (O) by the fluorine (F) atoms in these systems influences the glass structure. The iron ions modify in a different way the BO4/BO3 ratio, depending on the presence of the F or the O atoms in the glass matrix. (C) 2004 Published by Elsevier B.V.
