Analysis of structural relaxation in a Li2O2SiO2 glass using rate heating approach

摘要

The structural relaxation process of aninorganic glass (Li2O2SiO2)at different cooling rates has beenstudied by differential scanning calorimetry. A four-parameter model-Tool-Narayanaswamy-Moynihan(TNM)model was applied to simulate the normalized specific heatcurve measured. Four parameters, △h*/R, β,In A, and xwere obtained and compared with the values obtained fromthe isothermal approach.
