Preferred Abstract (Original):

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.
