Abstract  

Polytherm diagram of the ternary system KCl–FeCl2 –H2 O between 0 and 70C. Phase equilibria in the KCl–FeCl2 –H2 O system were studied over the temperature range 0–70C by conductimetric and analytical methods. A solubility polytherm of the system was constructed. We have observed the crystallization fields of the KCl and FeCl2 6H2 O (at 0C), KCl and FeCl2 4H2 O (at 15, 30 and 40C) and KCl, FeCl2 4H2 O and of a double salt KClFeCl2 2H2 O are obtained at 70C.

Abstract  

The phase diagram of ternary system Na+ , Fe2+ /Cl -H2 O was established over the temperature range 0–70C by conductimetric and analytical methods. A solubility polytherm of the system was constructed. For each temperature, we have determined the nature of the solid phase in equilibrium with the solution and the limit of its area of existence.
