Abstract
A melt quenching method has been adopted to synthesize the glasses 50Li2O–хMoO3–(50−х)P2O5 (х = 0, 5, 10, 15, 20, 25 and 27.5 mol%) which show the tendency of devitrification with increasing content of MoO3. The glass transition temperatures are found in the range between 332.3 °C and 361.9 °C when the glass forming domain at the fixed concentration of Li2O is limited to 0 ≤ x ≤ 27.5. Variation of local structure has been studied by Raman spectroscopy. The presence of different phosphate and molybdate structural units is observed. The electrical conductivity of the glasses at room temperature increases with x. The maximum conductivity is 5.0•10−7 S/cm in 50Li2O–27.5MoO3–22.5P2O5 composition at room temperature.
