Computer simulation of metastable zone width for unseeded potassium sulfate aqueous solution

Effect of sample volume on metastable zone width and induction time

“…The role of secondary nucleation in the measurements of MSZW and induction time was discussed recently by Kobari et al [8] and Kubota [15], where primary nucleation was assumed to occur progressively (not as a single event) and shown to have a significant effect on the measured values of MSZW and induction time.…”

“…Similarly as in MSZW, deterministic induction time t ind for a large vessel is related to the kinetics of primary nucleation and supercooling as follows [8]. If the solution concentration and the temperature remains unchanged (and hence the supercooling DT is constant), integrating Eq.…”

“…(21) and the deterministic induction time t ind calculated with Eq. (8). All the calculations were made for a supercooling of DT¼20 1C using the same primary nucleation kinetic parameters used for the above MSZW calculations.…”

“…The experimental data reported by Kadam et al [2] are analyzed using the proposed models. The deterministic MSZW for a large vessel can be related to the kinetics of primary nucleation and cooling rate as follows [8]. The number of crystals per unit mass of solvent (N/M) generated in a solution by primary nucleation by the time t elapsed from the start of cooling t ¼0 can be given by integrating primary nucleation rate per unit mass of solvent B 1 as…”

Comparison between approaches for the experimental determination of metastable zone width: A case study of the batch cooling crystallization of ammonium oxalate in water

“…In a recent series of papers, Kobari et al [17] proposed a unified approach of the many methods and experimental data related to the notions of MSZW and induction time [8,17,18]. Experimental and simulation results were systematically analyzed; it was shown that the different approaches reported in the literature are consistent and allow to understand the features of the nucleation process.…”
