The translation method of determining phase equilibria and construction of phase diagrams for multicomponent systems was applied to investigate the phase equilibria in two quaternary Na, NH4//SO4, Cl-H2O (at 100 °C, 10 °C) and Na2SO4-K2SO4-MgSO4-H2O (at 35 °C) and three quinary Li, K//Cl, CO3, B4O7-H2O (at 0 °C), Na, K//Cl, SO4, B4O7-H2O (at 50 °C), and Na, K//Cl, CO3, B4O7 - H2O (at 25 °C) water-salt systems. The comprehensive closed phase equilibria diagrams for each of the systems were constructed at the relevant temperatures. The constructed diagrams for the quinary systems were fragmented into trivariant crystallization volumes for each of the available individual solid phases in the systems. The available experimental results on each of the three investigated quinary systems compose only a portion of the phase equilibria data obtained by us using the techniques of translation method. Comparison of our results with the available literature data for the two quinary Li, K//Cl, CO3, B4O7-H2O (at 0 °C) and Na, K//Cl, SO4, B4O7 - H2O (at 50 °C) systems shows agreement. © 2016 American Chemical Society.

Phase equilibria in Na,K//SO4,CO3,HCO 3-H2O system at 50°C are studied by the translation method. 32 divariant fields, 36 univariant curves, and 13 invariant points are determined in the system. The first closed phase diagram (phase complex) of the investigated quinary system is constructed. The constructed phase diagram is fragmented into divariant fields of co-crystallization of the two phases at the quinary level. © Published under licence by IOP Publishing Ltd.

Phase equilibria in the quinary Na,K//SO4, CO3,HCO3·H2O system at 75 °C were studied by means of a translation method. A total of 34 divariant fields, 36 monovariant curves, and 13 invariant points are determined in this system. The first closed phase diagram (phase complex) of the investigated system is constructed. The constructed diagram is fragmented into divariant co-crystallization fields of two solid phases at the quinary level. Furthermore, it is fragmented into trivariant crystallization areas of all of 12 existing solid phases on the quinary level. © 2015 Springer Science+Business Media New York.

Phase equilibria of the Na,K,Mg,Na,K,Mg,Ca//SO4,Cl-H 2O system are studied at 50 C via translation in the crystallization range of glaserite (3K2SO4 · Na2SO 4). It is found that glaserite as the equilibrium phase of the investigated system at 50 C participates in the formation of 21 invariant points, 21 monovariant curves, and 34 divariant fields. A fragment of the phase equilibria diagram of the investigated system is constructed in the crystallization range of glaserite. © 2013 Pleiades Publishing, Ltd.

Phase equilibria in the Na,K∥CO 3,HCO 3,F-H 2O system at 50°C have been determined using the translation method. The system is found to be characterized by the existence of 21 divariant double-saturation fields, 19 monovariant triple-saturation curves, and six invariant quadruple-saturation points. A looped phase diagram (phase complex) for the title system at 50°C has been constructed. © 2012 Pleiades Publishing, Ltd.

Phase equilibria of the Na,K,Mg,Ca||SO4,Cl–H2O system at 50°С in the polyhalite (K2SO4 · MgSO4 · 2CaSO4 · 2H2O) crystallization region were studied using the translation method. Polyhalite was found to be involved, as an equilibrium phase of the title system at 50°С, in 17 invariant points, 36 monovariant curves, and 24 divariant fields. A fragment of equilibrium phase diagram of the title system in the polyhalite crystallization region was constructed. © 2016, Pleiades Publishing, Ltd.

Phase equilibria of the Na,K,Mg,Ca∥-SO4,Cl-H2O system at 50°C in the astrakhanite (Na2SO4 · MgSO4 · 4H2O) crystallization region were studied using the translation method. Astrakhanite was found to be involved, as an equilibrium phase of the title system, in 35 divariant fields, 39 monovariant curves, and 22 invariant points. The data gained were used to construct a fragment of a schematic equilibrium phase diagram of the title system in the astrakhanite crystallization region. © 2013 Pleiades Publishing, Ltd.

Abstract Phase equilibria of the Na,K,Mg,Ca∥-SO4,Cl-H2O system at 50°C in the sylvite (KCl) crystallization region were studied using the translation method. Sylvite was found to be involved, as an equilibrium phase of the title system at 50°C, in 15 invariant points, 37 monovariant curves, and 29 divariant fields. A fragment of a schematic equilibrium phase diagram of the title system in the sylvite crystallization region was constructed. © 2015 Pleiades Publishing, Ltd.

Phase equilibria at invariant points of the Na,K,Mg,Ca-SO 4,Cl-H2O system at 50°C in the anhydrite (CaSO 4) crystallization region were studied. Anhydrite as an equilibrium phase at the six-component level is involved in formation of 22 invariant points, 58 monovariant curves, and 49 divariant fields.
