Abstract

Nucleation and growth kinetics reveal valuable information about the crystal growth process, which can be employed in the growth of large size crystals. Since nucleation is the first step towards phase transition, a detailed knowledge about nucleation is of major importance for better control of crystallization or solidification. Investigations on nucleation thermodynamical parameters are very important for the successful growth of good quality single crystals. The metastable zone-width studies at different temperatures were carried out for L-Vallinium Picrate (LVP) crystal for different temperature range. The induction period and the critical nucleation parameters were calculated based on the classical theory of homogenous nucleation. The interfacial energy values for LVP crystal were calculated for different super saturation ratio. The growth parameters of LVP crystal were optimized..
