Abstract

Glasses were prepared in the pseudobinary system Li3B03−Li4GeO4 by a rapid quenching technique in the composition range of 8–80 mol% Li4GeO4. The structure of the glasses was examined by Raman spectra, X-ray diffraction analysis and molecular dynamics simulation. The coordination number of germanium atoms with respect to oxygen atoms in the glasses Li3B03−Li4GeO4 was shown to be higher than four by the X-ray diffraction analysis. The Raman spectra showed that not only monomer ions of BO 3 −3 and GeO 4 −4 , but also dimer B2O 5 −4 ions and six-coordinated GeO 6 −8 ions were present in these glasses over the whole glass-forming region. The presence of these ions was also confirmed from molecular dynamics simulation.
