Yc. Han et al., THE EFFECT OF STRUCTURAL PARAMETERS ON THE ENTHALPY RELAXATION OF AN INORGANIC GLASS (LI2O-CENTER-DOT-2SIO(2)), Materials chemistry and physics, 51(1), 1997, pp. 64-69
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. (C) 1997 Elsevier Science S.A.
