Abstract

One of the main applications of the stochastic matrix method is the evaluation of the probability of finding boroxol rings and dendrites in a boron oxide glass. In this work, we calculate the configurational entropy of B$_{2}O_{3}$ using this probability and Shannon's definition of entropy. The isentropic temperature is evaluated obtaining a very good agreement with experimental data. Entropy is introduced into the Adam-Gibbs equation to calculate viscosity. The resulting expression fits the complete range of temperatures for the supercooled liquid.
