Abstract  

The solid-liquid equilibria of the ternary system H2 O-Al(NO3 )3 -Mg(NO3 )2 were studied at 15, 25, 30, 40 and 50C by using a synthetic method which allows to determine all the characteristic points of isothermal sections. In all isotherms the liquidus exhibit two curves corresponding to the saturation in Mg(NO3 )2 ⋅6H2 O and Al(NO3 )3 ⋅9H2 O. Neither double salts nor mixed crystals are observed in the temperature and composition field studied.
