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.....
