摘要：

The structure and chemical properties of some vanadium boro-phosphate glasses of composition 25V(2)O(5) (40 - x)P2O5 xB(2)O(3) 20Na(2)O 15Fe(2)O(3) where x = 0, 10,..., 40 mol% containing iron oxide were thoroughly investigated, under the effect of replacing P2O5 by B2O3 in the glass network. These samples were structurally studied using X-ray, IR spectroscopy which reveals complex FTIR consisting of extended characteristic vibrational bands which are specific for phosphate groups as a main constituent but with the sharing of some vibrations due to the borate groups beside FeO4, FeO6 and VO5 units. The density, molar volume calculations and chemical durability were all studied and the results were discussed. (C) 2013 Elsevier B.V. All rights reserved.
