Заглавие : Glass formation and vibrational spectra of glasses in the RSO4-Na2B4O7-K2SO4 (R = Mg, Ca, Sr, Ba) systems Место публикации : Glass Physics and Chemistry. - 2006. - Vol. 32, № 6. - С. 634-637 Примечания : Библиогр. : с. 637 (10 назв.)

These regions are completely concentrated in the borate-rich region of the concentration triangle and occupy approximately 20% of the triangle area. The IR and Raman spectra of the glasses under investigation are recorded. It is revealed that the vibrational spectra of the glasses depend on the type of alkaline-earth metal cation. It is assumed that the structure of the glasses is determined by the glass-forming borate motifs with embedded sulfate anion tetrahedra.
