Abstract

The results of the StepScan® DSC obtained for 15Na2O⋅xMgO⋅(10–x)CaO⋅75SiO2 glasses were described in the frame of the commonly accepted theory of the glass transition. A new simplified model of the reversible part of StepScan® DSC record was developed on the basis of the Tool Narayanaswamy Moynihan relaxation theory. Equivalence between the formal activation energy of enthalpy relaxation process on one side, and the viscous flow activation enthalpy on the other side, was found.
