WebApr 12, 2024 · For application in crystallization, using a gas phase as a segmenting medium of the mother liquor is favorable to avoid contamination and further separation efforts to obtain the product phase. Within the liquid segments (slugs), the particles are suspended and induced to grow by imposing supersaturation as the driving force. WebThis is mainly because in electrochemical systems the driving force and the rate of crystallization can be measured and controlled with high accuracy by the electrode potential and the current.
WebThermodynamic driving force of crystallization The fundamental driving force for crystallization is defined as the difference between the chemical potential of the solute in the liquid and solid phase.
