ABSTRACT:

Fractional crystallization of two isomorphous systems of the picromerite type has been investi-gated for mixtures with different fractions from the less soluble component. The results at 0,20, and 300C for the equilibrium or non equilibrium states were discussed in terms of the theory given before1. The empirical relation between the distribution coefficient and the picromerite solubilities was also studied and reported herein. Rozeboom square diagrams were investigated to confirm the ideality of the separated solid solutions.
