Studies on growth, induction period, interfacial energy and metastable zonewidth of m‐nitroaniline

Abstract

Single crystals of m-Nitroaniline (mNA) were grown by slow cooling solution growth technique. Induction period, interfacial energy and metastable zonewidth have been evaluated. The solubility of mNA has been estimated at different temperatures in acetone and ethanol. 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.

Studies on Nucleation, Growth and Characterization of L-Leucine Doped ZTS Crystals

“…The critical nucleation parameters such as radius of critical nucleus, Gibbs free energy change and number of molecules (n) in the critical nucleus decrease with supersaturation ratio (S) and these parameters decrease when concentration of dopants is increased. The obtained results of this work were the same as observed by other authors for their systems [20][21][22][23]. In accordance with the solubility data, saturated solutions of the synthesized salts of pure and L-leucine doped ZTS were prepared separately.…”

Investigations on nucleation kinetics, growth and characterization of sulphanilic acid single crystals

“…It is done to have uniform temperature and concentration throughout the volume of the solution. After attaining supersaturation, the equilibrium concentration of the solute was analyzed gravimetrically [10]. The same process was repeated for various temperatures 40°C, 45°C, 50°C and 55°C and the solubility of SAA was estimated ( fig.…”

Investigations on nucleation, thermodynamical parameters and growth of Benzimidazole crystals from low temperature solution

“…Several trials were carried out to arrive at the optimized conditions. To measure the metastable zone width, conventional polythermal method [4] was employed. In this method, the equilibrium-saturated solution was cooled from overheated temperature under stirred condition until a first perceptible crystal was observed.…”

“…Induction periods were recorded for different supersaturation ratios of 1.15, 1.20, 1.25, 1.30, 1.35, 1.40, 1.45, 1.50, 1.55 and 1.60. The induction period [4][5][6] is written as,…”
