The phase solubility diagrams of water-salt systems geometry in case of simple evtonic type

The phase solubility diagrams of water-salt systems common structure was described in case of simple evtonic type without crystalline hydrate and hard solutions. The method of figurative points position determination relatively to the simplex in multidimensional space was described. The algorithm of random figurative points phase area detection in phase solubility diagram was described in case of 4-component water-salt systems of simple evtonic type without crystalline hydrate and hard solutions. The solid and liquid equilibrium phase calculation method was described. The physicochemical characteristics calculation method was described to points on liquidus boundary by experimental data. The mathematical content of visualization program module was presented and illustrated by phase solubility diagram of 4-component water-salt systems examples.
