crystallization




The process of forming crystals by a substance passing from a gas or liquid to the solid state (sublimation or fusion) or coming out of solution (precipitation or evaporation). In the fusion method a solid is melted by heating, and crystals form as the melt cools and solidifies. Ice crystals and monoclinic sulfur are formed in this way. Crystallization is an important laboratory and industrial technique for purifying and separating compounds.
