From differential scanning calorimetry (DSC) measurements
performed on Ge40S60 chalcogenide glass forming liquid, the values of the
apparent activation energy Δh*, and the fragility index, m, as defined in the
strong-fragile glass forming liquid concept, have been determined. The
calculated value of m for this glass forming liquid is equal to 82. From this m
value, it is suffice to conclude that this glass forming liquid belongs to an
intermediate category that exhibits a kinetic behaviour between strong and
fragile.
