Abstract :The dependence of the induction period of crystallization on super cooling was determined for the system lithium chloride—potassium acid phthalate insert ignore into journalissuearticles values(KAP); over the composition of 1mole % LiCl2. This dependence can be described by 1/ insert ignore into journalissuearticles values( lnS); 2 against ln τ curve. In order to reduce the effect of heterogeneous nucleation on the nucleation parameters, the interfacial energy was calculated from the slopes determined in the linear region of the line plots. Nucleation parameters like free energy change, rate of nucleation and critical radius were determined using the value of interfacial energy. Correction was made to the interfacial energy based on the thermodynamically approach. An attempt has been made to calculate the nucleation parameters corresponding to the critical super saturation ratio using the modified classical nucleation theory
