Abstract Experiments have been done to determine the extent to which the nucleating ability of 50: 25: 25 mol% composition of Agl, AgBr and Cul fusion material is influenced by the presence of soluble salts. Using a bulk freezing technique, the freezing nucleation temperatures are measured for each salt combination with the nucleant, at salt concentrations of 0.01, 0.1 and 0.5 M. For this, 21 soluble salts have been considered. These salts are found, in general, to increase the supercooling to varying amounts depending upon the salt type and the concentration. But NaCl, at 0.01 M concentration significantly improved the nucleation ability of the material and the nucleation temperature was found to be as high as −0.35° C. The combination of chlorides as well as some sulphates are found to exhibit a decrease in nucleation activity of the material.
