For a binary system, this approach is equivalent to using polynomial truncated expansions, such as the Redlich-Kister series for describ- ing integral thermodynamic quantities. For ternary systems, an equivalent expansion of the excess chemical potentials clearly justifies the inclusion of ternary interaction param- eters, which arise naturally in the form of correction terms in higher-order power expansions. To demonstrate this, we carry out truncated polynomial expansions of the excess chemical potential up to the sixth power of the composition variables 2014 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46431122004 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.2-3 Vol.44 |
