Abstract

We describe the mean-field global phase diagram for a Widom-type lattice mixture of bifunctional molecules ab and AA with general finite interactions. Our results follow from the known features of the phase diagrams along the symmetric sections of Griffithss three-component (spin-1) model when both uniform and sublattice-ordered states are considered. The properties of the mixture are analogous to those of a binary alloy with one magnetic component. We find first- and second-order transitions between uniform fluid states and five different types of ordered phases.
