Abstract
The boron alkali molybdate glass system was investigated as lead-free low-temperature melting sealing materials, with different boron oxide contents between 0 and 8 mol%. The glasses were characterized using X-ray diffraction (XRD), differential scanning calorimetry (DSC), infrared spectroscopy (IR), and by densities. Their chemical properties were measured by their dissolution..... More

Abstract
In this study, quaternary phosphate-based sol-gel derived glasses were synthesized from a P₂O₅-CaO-Na₂O-TiO₂ system with a high TiO₂ content of up to 50 mol%. The sol-gel method was chosen because incorporating a high percentage of titanium into a phosphate network via traditional melt-quench methods is non-trivial. The structure and thermal..... More

Abstract
As with any solvent, stabilizing a multivalent element at a given oxidation level in the glass depends on the thermodynamic conditions. The effects of temperature in the oxidation-reduction equilibrium have been previously noted with higher temperatures being conductive to reduced states. 30Ce₂O-70P₂O₅ binary system glasses were prepared. The effects of..... More

Abstract
In this study, we established a correlation between the electrical conductivity and catalytic properties of vanadium borophosphate glass containing Fe₂O₃. Glasses were synthesized in the 78V₂O₅–15P₂O₅–7B₂O₃ ternary-system containing x mol% Fe₂O₃ (x = 1, 5, 7.5, and 10). Electrical conductivity was measured at 45 ℃ for samples heat-treated at 340.....
