Abstract :
In studying the order parameter and configurational entropy of model albite a new method, the sequential construction method, has been developed. As a test,first it was used for Andersen,s one-dimensional model of albite. Very good results were obtained, namely for the configurational entropy (a maximum difference of 2,from the exact value was observed). The model was then used for Andersen,s two-dimensional model of albite. In comparison with the Monte Carlo results, this method gives better results than the quasi-chemical calculation of Mazo and Andersen.
