Abstract

The infrared, optical absorption spectra and electrical conductivity of sodium-digerminate glasses containing iron oxide have been studied as a function of iron content. Addition of iron does not introduce any new absorption band in the infrared spectrum of pure sodium-digermanate glass. A small shift of the existing absorptions toward lower wavenumbers is observed. These are in agreement with the spectra of Fe₂O₃Na₂O2SiO reported earlier. The optical absorption spectra also indicated that the non-bridging oxygen present in pure sodium-digermanate glass was unaffected by the addition of Fe₂O₃ in a small quantity. The DC conductivity measurements revealed "mixed conduction" phenomenon in which ionic as well as electronic conduction occur in the glass.
