چکیده

Abstract For the ternary (60 - x)V2O5–40TeO2–xNiO glasses with 0 B x B 20 (in mol%), the glass transition temperature (Tg) and crystallization temperature (Tcr) have been determined using differential scanning calorimetry (DSC) at heating rates u = 3, 6, 9, and 12 K/min. The effect of the heating rate and the NiO content on Tg is discussed. It was observed that the transition region shifts to higher temperatures when the measuring time is reduced (or, conversely, when the applied temperature rate is increased). Using DSC, the compositional dependence of Tg has been determined and so, an empirical equation has been deduced which relates the glass transition temperature with the NiO content.
