Synthesis of Tungsten Phosphate Glasses and Study of Their Thermal Properties

Аннотация

xWO₃–(100–x)P₂O₅ (70 mol % ≤ x ≤ 82 mol %) glasses were obtained by melt quenching. Their thermal properties were studied by the DTA method. It was found that the rise of WO₃ сontent leads to a decrease in thermal stability of glasses and lower glass transition and crystallization temperatures. The compositions 70WO₃–30P₂O₅ and 75WO₃–25P₂O₅ are not crystallized in the temperature range 35–950°C.
