Abstract

As an extension of previous works, we analyse regularity in disordered Al/Si distributions in phyllosilicates 2:1. The method is based on an analysis of maximal independent sets in a labelled quotient graph of the net. The results, similar to those obtained through the principle of homogeneous dispersion, are in quantitative agreement with published 29Si MAS NMR intensity data for muscovite, phlogopite and vermiculite. The method also allows an easy construction of structural models considering disorder and non-stoichiometry.
