A study of TeO2-P2O5 glass system has been carried out by Differential
Thermal Analysis (DTA) to elucidate the kinetics of crystallization f
or these glassy samples. The results of DTA performed at different hea
ting rates are discussed. The values of the glass transition temperatu
re, T-g, as well as the glass crystallization temperature, T-c, are fo
und to be dependent upon the heating rate. From this dependence, the v
alues of activation energy for both the glass transition and crystalli
zation are evaluated and discussed.
