Phase Diagram of the Quaternary Al(NO3)3-Cu(NO3)2-Zn(NO3)2-H2O System

Résumé

The phase diagram of the H2O-Zn(NO3)2-Al(NO3)3-Cu(NO3)2 quaternary system at 30 °C has been established by using the conductivity measurements. The solid-liquid equilibria of the H2O-Zn(NO3)2-Al(NO3)3, H2O-Zn(NO3)2-Cu(NO3)2, H2O-Al(NO3)3-Cu(NO3)2 ternary systems and two isoplethic sections were determined experimentally. The solid phases in equilibrium with the saturated solution are the tri- and hemipentahydrate of copper nitrate, the hexahydrate α and β of the zinc nitrate and the nonahydrate of aluminum nitrate. The copper and zinc nitrates are relatively soluble in opposition to the aluminum nitrate which presents some important precipitation domains.
