摘要

Glass formation behavior of the TeO_2-WO_3-Na_2O system was studied by using conventional melt-quenching technique. A wide glass formation range was determined for the first time in the literature and thermal, physical, and structural characterization of sodium-tungsten-tellurite glasses were realized using differential scanning calorimetry (DSC) and Fourier transform infrared (FTIR) spectroscopy techniques. Glass transition (T_g) and crystallization (T_c/T_P) temperatures, glass stability (△T), density (p), molar volume (V_M), oxygen molar volume (V_o), and oxygen packing density (OPD) values and structural transformations in the glass network were investigated according to the equimolar substitution of TeO_2 by Na_2O+WO_3 and changing Na_2O or WO_3 at constant TeO_2.
