Infrared Spectra of Fe2O3-Li2O-B2O3-MoO3 Glasses

Abstract

Changes in network structures of lithium-molybdenum-iron-borate
glasses were investigated by means of infrared spectroscopy
and X -ray analysis. Analysis of the network structures were carried
out based on a (1) networks unmodified by MoO₃ and (2) Fe₂O₃-
modified network. The unmodified networks are made by three
dimensional array of clusters with unmodified BO₃ and BO₄ groups.
MoO₃ reduction and FeZO₃ addition both gives contribution to four
coordinated boron which governs the glass structure.
