[ 13] found that solute concentration-mediated supersaturation can trigger crystal nucleation and polymorphism by varied solute concentration. Sometimes nucleation and metastable region coexist. Lower supersaturation is more helpful for I and moderate supersaturation more conducive to II Nucleation.
WebOct 6, 2024 · However, we speculate that the promotion of mineral nucleation is related to the liquid–liquid phase separation, during which PNCs become nanodroplets that can subsequently yield either ACC or crystalline particles. Potentiometric titrations also elucidate the nature of mineral products [ 26, 28 ].
