Abstract

Structural properties of alkali borosilicate glasses containing iron ions were investigated using infrared, laser Raman and Mössbauer spectroscopy. Two types of glasses were prepared: SRL-type with the composition 18.5 wt% Na2O, 10.0 wt% B2O3, 52.5 wt% SiO2, 4.0 wt% Li2O, 10 wt% TiO2 and 5.0 wt% CaO, and sodium borosilicate glass with the composition 16.7 wt% Na2O, 18.7 wt% B2O3 and 64.6 wt% SiO2. Raman spectroscopy showed that orthosilicates are the dominant amorphous phase in the SRL-type of glass. Incorporation of iron in the SRL-type of glass induced polymerization of silicate units and -Si-O-Fe- copolymerization. It was concluded that different amorphous phases are simultaneously present in the SRL-type of glass containing iron ions. Interpretation of the Raman spectra is given. Incorporation of iron ions into the sodium borosilicate glass also affected the corresponding IR spectra. The valence state of iron and its coordination were determined by57Fe Mössbauer spectroscopy.
