[en] The phase equilibria of system have been studied by means of translation method, which follows from the Gibbs phase rule and the basic principles of physicochemical analysis, the structural elements of diagrams of partial component systems with elements of general component system in one diagram. Regularities of phase equilibria in system, which determines the conditions for the complex processing of complex poly mineral natural and technical raw materials. It has been found that studied system at 75 deg C is characterized by the presence of 7 di variant fields, 12 mono variant curves of invariant points. On the basis of data obtained, its phase diagram has been constructed for the first time. In studied system, at the level of four-component composition, a new phase appears - polyhalite with equilibrium of four phases. (author)

[en] The phase equilibriums in the system Na, Ca//SO4, CI-H2O at 0 Deg C have been studied in given paper. By means of translation method, it has been defined that Na, Ca//SO4, CI-H2O system at 0 Deg C characterizes by the presence of 2 invariant points, 5 mono variant curves and 4 di variant fields. The diagram of phase equilibria of the system at 0 Deg C has been constructed for the first time. (author)
