Abstract
The phase diagram of the HO-Zn(NO)-Al(NO)-Cu(NO) quaternary system at 30 °C has been established by using the conductivity measurements. The solid-liquid equilibria of the HO-Zn(NO)-Al(NO), HO-Zn(NO)-Cu(NO), HO-Al(NO)-Cu(NO) 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. [ABSTRACT FROM AUTHOR]
