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

Material Analysis & Characterization

Abstract
In order to strengthen the structure of the glass and ultimately improve its water resistance, P₂O₅–ZnO–Bi₂O₃ was doped with Fe₂O₃, which generated Fe ions in the phosphate-based glass. These ions constitute (P₂O₇)⁻⁴ groups within the glass network. Structural analysis using Fourier transfer infrared spectroscopy indicated that P-O-P and Bi-O-P bonds..... More
