Crystallization is the process of forming a crystalline structure from a fluid or from materials dissolved in a fluid. (More rarely, crystals may be deposited directly from gas; see thin-film deposition and epitaxy.) Crystallization is a complex and extensively-studied field, because depending on the conditions, a single fluid can solidify into many different possible forms… WebApr 8, 2024 · Crystallization is a process of formation of a solid in which atoms and molecules are structured in such a way that they are highly organized. The structure in which they are structured is called a crystal.
