Antagonism of phases in multi-component mixtures

The phase composition of multi-component systems is analyzed. In the process of the study the effect of phase antagonism was observed, the effect revealed itself in the form of correlation between the percentage composition of individual phases in a multi-component mixture, with the percentage composition of the other phases remaining almost unchanged. On the basis of experimental studies, the examples of such phases in multi-phase mixtures are pairs of monoclinic pyrrhotite and somolnokit, goethite and troilite, hexagonal pyrrhotite of different composition and monoclinic pyrrhotite.
