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 ]. WebSolution crystallization is the transformation of a substance from liquid state to crystalline state and its process undergoes two steps, which are nucleation and crystal growth. Nucleation is the generation of a number of crystal nuclei in the supersaturated solution and crystal growth is the further growth of crystal nuclei.
