Crystallization: Basic Concepts and Industrial Applications

WebIn layer crystallization the crystals grow onto a cooled surface. Crystals grow in a non-adiabatic environment in such a way that subcooling is supplied through the crystal layer rather than through the liquid phase. The driving force results from the net effect of temperature and concentration gradients across both the solid and liquid phase. 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.
