abstract:
The structural relaxation process of an inorganic glass (Li2O · 2SiO2) at an ageing temperature of 703 K for an ageing time of 1 h has been studied by differential scanning calorimetry. A four-parameter model - the Tool-Narayanaswamy-Moynihan (TNM) - model was applied to simulate the normalized specific heat curve measured. A set of optimized parameters, ? h*/R, ?, In A, and x was obtained. Then the effects of variation of each adjustable parameter on the calculated specific heat were summarized.
