“…where the value of g mostly falls between 1 and 2. Based on Burton-Cabrera-Frank (BCF) growth theory [28][29][30], the value of g is found close to 2 for low supersaturations [31]. Mohan and Myerson [32] indicated for aqueous L-glycine solutions at 293.15 K that Equation (4) with g = 2 is consistent with the BCF growth kinetics reported by Li and Rodriguez-Hornedo [33].…”

As the turbidity induction time measurements are influenced by the size distribution of the nuclei at the detection point, these data should provide important information on both nucleation and growth. A model is developed in this work to determine the nucleation and growth kinetics of aqueous L-glycine solutions using the turbidity induction time data for various supersaturations from 293.15 K to 313.15 K. The photomicroscopic growth experiments of aqueous L-glycine solutions are also conducted to determine the growth kinetics of nuclei under the same conditions for comparison. The results indicate that the interfacial energy obtained from this model is consistent with that obtained based on the traditional method by assuming t i − 1 ∝ J . The growth kinetics, including the growth activation energy and the kinetic growth parameter, obtained from this model using the induction time data are close to those obtained from the photomicroscopic growth experiments performed in this work.

The surface micromorphology of the {101} faces of potassium dihydrogen phosphate (KDP) crystals grown at different supersaturation conditions is systematically compared using atomic force microscopy. The height and width of the crystals during different growth steps are measured. The pyramidal face growth rate of KDP crystals is tested by a laser polarization interference system. The X-ray rocking curve is used to measure the structural perfection of the {101} face of the KDP crystals. The results show that the growth rate of the {101} face increases with the supersaturation degree, and the rate is faster than that of the {100} face at a low supersaturation degree. Step bunching first increases and then decreases upon increasing the supersaturation, and the step height reaches a maximum value of about 6.0-6.9 nm at 𝝈 = 0.08 and 0.09. The crystal structural perfection is the worst under these conditions. It should be noted that 2D nuclei form on the surface terraces when the supersaturation is about 0.07. Dendrite-like steps may be formed due to the development of these 2D nuclei. This work provides a reference for further researching the step evolution law of other crystalline materials.

“…Compared with the growth at low temperatures, the ability to reject foreign impurities was enhanced at high temperatures. 7,40 Hence, crystal growth was less affected by impurities at a high temperature. Hence, if supersaturation and the temperature are high, the growth rate accelerates.…”
