Abstract

It has been known for > 60 years that thermal events taking place during DTA measurements (e.g. glass transition or crystallization) depend on heating rate. In this paper, we collected numerous data of DTA measurements of various glasses containing transition metal oxides (V2O5, FeO, Ti2O3) carried out at different heating rates (1 to 25 °C/min). We showed that glass transition temperature vs. heating rate can be well described by both Kissinger's and Lasocka's formulas. Additionally, we discuss an accuracy of extrapolation based on data taken at high heating rates to low heating rates. Our result show that glass transition temperatures at low heating rates can be satisfactorily extrapolated from higher ones, with a relative error < 3.5% in every case (and mostly < 1%), due to linear change with heating rate both in Kissinger's and Lasocka's plots. © 2016 Elsevier B.V.
