Abstract

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.
