Borosilicate Glass Structure With Rare-Earth-Metal Cations Substituted For Sodium Cations

IR and RS spectroscopy are used to study the effect of substituting barium and calcium for the sodium cation on the structure of sodium borosilicate glass with the composition 0.25Na2O; O.25B2O3; 0.5SiO2. Analysis of the recorded spectra showed that the substitution of the alkali-metal cations Ba2+ and Ca2+ for the Na+ cation results in breaking of B-O-B and Si-O-Si bridges, as a result of which the fraction of oxygen end atoms increases and the degree of polymerisation of the glass decreases.
