This paper is the second part of the analysis using the polyassociative solutions model (PAS) to determine the phase equilibrium of A(2)B(6) semiconductor compounds and magnetic oxide solid solutions, crystallizing into a spinel structure. The first part [1] presented the general characteristics of the PAS model and its application in the analysis of binary compounds. This second part of the paper defines the advantages and disadvantages of using the PAS model in the construction of p-T-x phase diagrams of A(2)B(6) semiconductor compounds and ternary magnetic oxide solid solutions, crystallizing into a spinel structure. The results of the theoretical analysis were compared with the experimental data. (C) 2012 Elsevier B.V. All rights reserved.
