Structural, dielectric and optical properties of SrB₄O₇–BaO–TiO₂ glasses

Glass samples with compositions (100–2x)SrB₄O₇–xBaO–xTiO₂ (10≤x≤40) were prepared by conventional melt quenching and the influence of the addition of BaO–TiO₂ on the structural, dielectric and optical properties of SBO glasses was studied. The molar volume, glass transition temperature and the optical polarisability of the glass samples were found to decrease with increase in BaO–TiO₂ content while the refractive index and optical band gap increase with increase in BaO–TiO₂ content.
