Abstract
Five series of Na2O-FeO-Fe2O3-P2O5 glasses with compositional ranges of 3.0Â <Â O/PÂ <Â 3.5 and 0Â <Â Fe/PÂ <Â 0.67 were prepared. Glass structure was studied using Raman spectroscopy and Mössbauer spectroscopy. For glasses with similar O/P ratios, an increase in the Fe/P ratio produced broader distributions of phosphate anions, as indicated in the Raman spectra, and the average coordination number (CNFe) of the Fe ions decreased, as indicated by the Mössbauer data. The interaction between phosphate anions and iron polyhedra causes systematic changes in the Raman frequencies as well as peak intensities.
