Partition of the Quaternary Reciprocal System Na,K∥Cl,I,CrO4 and Investigation of Its Stable Elements
Investigation of multicomponent salt systems is important in the context of the wide use of invariant mixtures as electrolytic media for separation of metals and heat-storage materials. In this work, the quaternary reciprocal system Na,K∥Cl,I,CrO 4 was partitioned into simplexes using graph theory....
