Phase Complex of the System Na,K,Mg,Ca∥SO4,Cl–H2O at 50°С in the 2MgCl2 · CaCl2 · 12H2O and CaCl2 · 2H2O Crystallization Fields

The phase complex of the system Na,K,Mg,Ca∥SO 4 ,Cl–H 2 O at 50°С in the 2MgCl 2 · CaCl 2 · 12H 2 O and CaCl 2 · 2H 2 O crystallization fields has been predicted and constructed using the translation method. 2MgCl 2 · CaCl 2 · 12H 2 O and CaCl 2 · 2H 2 O are involved in the formation of the following numbers of geometric images of the title system: three and one invariant points; 10 and 4 monovariant curves; and 12 and 6 divariant fields, respectively. The phase complex of the title system has been fragmented into divariant fields.
