It was found that the crystals coalesced through contact nucleus-bridges between them according to the mechanism proposed by Polak. The kinetics of aggregation were described by the Smoluchowski equation for coagulation of colloidal particles. The kinetic coefficient of aggregation process depended on supersaturation, temperature of solution and other characteristics of the system. The specific surface energy of sodium chloride 0.95 mJ/m2 was found
