文摘
- •
Glasses containing transition metal oxides were obtained by melt-quenching method.
- •
Their glass transition temperatures (Tg) were evaluated using DTA method.
- •
Results were analyzed due to applicability of Lasocka's and Kissinger's formulas.
- •
Experiments showed that in both coordinates dependence of Tg and θ is linear.
- •
Tg point for low heating rates can be extrapolated from higher ones.
