“…This observation suggests that very different growth rates, and therefore different aspect ratios, should be observed for the [1 1 0] face in the two solvents. This is in complete agreement with the morphologies observed experimentally, where the [0 0 1]/ [1 1 0] aspect ratio of urea crystals grown from methanol can be orders of magnitude smaller [20] than the aspect ratio of crystals grown from aqueous solutions [21].…”

The growth of urea crystals from water and methanol solutions has been studied with kinetic Monte Carlo simulations. Parameters for the simulations were derived from atomistic molecular dynamics simulations of the growth and dissolution of urea from water and methanol solutions. This approach allows the effect of solvation on the growth and dissolution kinetics to be fully included while extending the size of the simulation to the micrometre length scale and millisecond timescale. r

“…The mechanism by which F faces grow is therefore an important factor affecting crystal morphology. Davey et al (1986) applied the dislocation theory of growth developed by Burton et al (1951)-the BCF surface diffusion model-to analyze the kinetics of crystal growth in the presence of tailor-made additives, According to Black et al (19861, the adsorption of tailor-made additives on crystal surfaces generally occurs on step sites as viewed by the Albon and Dunning (1962) model. In that model, spontaneous fluctuations produce kinks along the entire length of the step.…”

“…In order to isolate the crystals which exhibit the desired physical properties, the fundamental process of crystal growth and its associated kinetics need to be understood, characterised and controlled. Previous studies in this area have mostly presented measurements of growth rates of single crystal seeds grown at comparatively low supersaturations [1][2][3][4][5][6]. Alternatively, measurements have been made of the growth rate of a population of crystals as prepared under crystallisation reactor environment conditions e.g.…”

The crystal growth rates of the {001} and {011} faces of spontaneously nucleated crystals are precisely measured in-situ using optical microscopy revealing that their respective growth rates increase with increasing supersaturation to different extents, depending on the solvent type, with concomitant impact on the crystal habit. The measured aspect ratios, as a function of supersaturation, are generally higher at the 15 mL than the 0.5 mL scale size.Analysis of the growth rates versus supersaturation is consistent with a 2-D surface nucleation (Birth and Spread) model for both faces and at both scale sizes. The growth rates of the {001} and {011} faces exhibit much less growth rate dispersion when compared to literature data for a stirred batch crystallizer. 2The data is rationalized by examining the surface chemistry of the growing faces revealing, e.g. that polar protic solvents inhibit the growth rate of faces containing available binding sites for hydrogen bonding formation, such as carboxylic acid groups.
