Abstract
The kinetic reactions mechanism of amorphous to crystalline transformation in the chalcogenide glasses of As
50
Se
50
composition was investigated using differential scanning calorimetry (DSC) data measured under non-isothermal conditions at different heating rates (
β
= 5, 10, 20, 30 and 40 k min
−1
). The DSC data were analyzed using the integral
g
(
χ
) and differential
f
(
χ
) forms which describes the solid-state reactions mechanism utilizing the Ozawa approach. The crystallization activation energy of
E
c
(
χ
) was determined using the iso-conversional methods proposed by Friedman, Flynn–Wall–Ozawa and Kissinger–Akahira–Sunose. The results revealed a slight increase of
E
c
(
χ
) with the conversion (
χ
). The results of
g
(
χ
),
f
(
χ
) and combination
g
(
χ
)
f
(
χ
) master plots showed that the As
50
Se
50
chalcogenide glasses is a combination of two- and three-dimensional crystal growth.
