content from 20 to 40% was investigated by high-temperature Raman spectroscopy. It was shown that when the boron oxide content was gradually increased, the silicate network undergoes depolymerization, which is confirmed by the change in the ratio of the intensities of the bands characteristic of tetrahedrons with a different number of nonbridge oxygen atoms (

and

). The borate constituent has BO

tetrahedrons which then alternate with nonsymmetrical BO

triangles with nonbridge oxygen atoms.
