Thermal stability and transport studies of (100 − 2x)TeO2-xAg2O-xWO3 (7.5 ≤ x ≤ 30) glass system

▶ The addition of equal mol% of WO3 and Ag2O to TeO2 increases the thermal stability. ▶ The 55TeO2-22.5WO3-22.5Ag2O shows the highest thermal stability (ΔT = 237 °C). ▶ These glasses are more useful for drawing of optical fibers. ▶ The present glass system shows higher conductivity.
