METHOD OF DETERMINING COMPOSITION OF EQUILIBRIUM SOLID PHASES IN MULTI-COMPONENT WATER-SALT SYSTEMS Russian patent published in 2008 - IPC G01N33/18 G01N31/00 

FIELD: physical and chemical analysis.

SUBSTANCE: carried out by determining compositions of nonvariant solutions saturated with n-2 and n-1 salts, and calculating the component ratio using a straight-line equation, the coordinates of borders of nonvariant areas of isohydric sections in (n-1)- and apexes in n-component systems are determined experimentally without separating the equilibrium phases, and compositions of equilibrium solid phases are determined by identifying the intersection point of two limit nodes predetermined by the compositions of the corresponding nonvariant solutions and borders or apexes of novariant areas.

EFFECT: decrease in labour consumption and increase in determination reliability.
