Structure-Property Relations in Barium Borate Glasses from Raman Scattering Data
Glasses in the xBaO-(100 - x)B^sub 2^O^sub 3^ system (x = 16-50 mol %) are investigated by Raman spectroscopy. The spectral forms of stoichiometric groupings are separated from the experimental Raman spectra. The diagram of the content of these groupings in glasses is constructed. The diagram obtain...

Summary: | Glasses in the xBaO-(100 - x)B^sub 2^O^sub 3^ system (x = 16-50 mol %) are investigated by Raman spectroscopy. The spectral forms of stoichiometric groupings are separated from the experimental Raman spectra. The diagram of the content of these groupings in glasses is constructed. The diagram obtained makes it possible to calculate the densities, refractive indices, temperature coefficients of linear expansion, and fractions of four-fold-coordinated boron atoms with the use of the experimentally determined partial properties of the groupings. It is revealed that the dependences of the boson peak intensity, the boson peak frequency, and the glass transition temperature on the composition of glasses in the barium borate system correlate with each other.[PUBLICATION ABSTRACT] |
