Description 429-440
The glasses, composed of multiple components, contain chromium oxide x.Cr2O3.(70-x)B2O3.18Bi2O3.12Na2O, where x
varies (x=0, x=0.15, x=0.25, x=0.35, x=0.50 mol %), synthesized using the melt-quench method. The amorphous nature of
the synthesized samples was confirmed using X-ray diffraction (XRD). We observed that an increase in Cr2O3 content
resulted in a rise in the density (ρ) of the glasses, ranging from 3.88 g/cm3 to 4.009 g/cm3. Notably, the molar volume
displays behaviour opposite to the density trends. The oxygen packing density (OPD) exhibited augmentation with elevated
chromium oxide concentrations, implying a more compact and tightly packed glass structure. Fourier transform infrared
(FTIR) spectroscopic data show distinct features of the synthesized glass samples corresponding to chromium oxide content.
The FTIR spectra display vibrations of metal cations and Cr3+ at around 530 cm−1, and a band at approximately 1150 cm−1,
attributed to the B-O bonds with non-uniform stretching vibrations in [BO3] units. The analytical findings indicate the
predominant presence of [BiO6], [BiO3], and [BiO4] vibrations in the glasses. The Raman spectroscopy affirms the presence
of distinct structural units, including BiO3, BiO6, BO3, and BO4. These findings provide a foundational basis for customizing
glass compositions to meet specific technological requirements, encompassing applications in optics and radiation shielding.
