| Abstract Scope |
Thermal behavior and kinetics of glass transition in B<SUB>2</SUB>O<SUB>3</SUB> containing tungsten-tellurite glasses was studied by using differential scanning calorimetry (DSC) and X-ray diffraction (XRD) techniques. Different compositions of the 0.80TeO<SUB>2</SUB> - (0.20-<I>x</I>)WO<SUB>3</SUB> - <I>x</I>B<SUB>2</SUB>O<SUB>3</SUB> system (0 ≤ <I>x</I> ≤ 0.20 in molar ratio) were prepared with conventional melt-quenching technique at 750 °C and it was aimed to investigate the effect of B<SUB>2</SUB>O<SUB>3</SUB> addition on the thermal behavior of tungsten-tellurite glasses. The kinetics of glass transition was studied under non-isothermal conditions and the glass transition activation energy, <I>E</I><SUB>g</SUB>, was determined by modified Kissinger equation. |
