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.
