Crystallization's the (natural or artificial) process of formation of solid crystals precipitating from a solution, melt or more rarely deposited directly from a gas. Crystallization's also a chemical solid-liquid separation technique, in which mass transfer of a solute from the liquid solution to a pure solid crystalline phase occurs. Process The crystallization process consists of two major events, nucleation and crystal growth. Nucleation's the step where the solute molecules dispersed in… (More on Crystallisation)
