✦ Synopsis

The solubility, metastable zone width and induction period have been determined for the solution grown methyl-para-hydroxy benzoate (MHB) single crystals. Nucleation parameters such as Gibbs free energy, radius of critical nucleus, critical free energy barrier and number of molecules in the critical nucleus and nucleation rate have also been investigated. Interfacial energy has been estimated using the experimentally determined induction period values. It is observed that the nucleation rate increases with the increase of supersaturation. The evaluated interfacial tension values are found to be comparable with the theoretical values. The growth parameters of MHB were optimized for the growth of large size crystals.
