The solid-liquid equilibrium of the ternary system of H2O-Al (NO3)3-Ni (NO3)2 were studied using a synthesis process based on conductivity measurements. Three isotherms included between 20 and 40°C were determined and the stoichiometric phases that appear are Al(NO3)3.9H2O and Ni(NO3)2.6H2O, it was found that there is one eutectic point and two crystallization regions corresponding to Aluminium nitrate and Nickel nitrate. The system belongs to a simple co-saturated type, and neither double salts nor solid solution was found.
