Abstract
The structural relaxation process of an inorganic glass (Li2O . 2SiO(2 )) at an ageing temperature of 703 K for an ageing time of 1 h has bee n studied by differential scanning calorimetry. A four-parameter model -the Tool-Narayanaswamy-Moynihan (TNM)-model was applied to simulate t he normalized specific heat curve measured. A set of optimized paramet ers, Delta h/R,beta,InA, and x was obtained. Then the effects of vari ation of each adjustable parameter on the calculated specific heat wer e summarized.
