A GENERAL-SOLUTION MODEL FOR PREDICTING TERNARY THERMODYNAMIC PROPERTIES

All current models used to predict ternary thermodynamic properties from binaries improperly assume that the selected binary compositions in a ternary model are independent of ternary considered. As a result, it will require human interference for selecting models and arranging components to three apexes of a triangle, and will lead to an unacceptable result in some limiting case. A reasonable assumption should be that the selected binary compositions are closely related to the ternary itself. On the basis of this idea, a completely new model has been suggested. It seems that this new model is more reasonable theoretically from consideration, more reliable in practical application and more realistic to use in computerized thermodynamic and phase diagram calculation.
