Control over crystallizations is critical in achieving critical quality attributes and there are a significant number of interacting factors that influence crystallinity affecting crystal size particle size distribution polymorphism etc.

Crystallization also known as Crystallisation is the process where a solid formed into a structure of the crystalThe commonly seen methods of crystallization are by precipitating or freezing from a solutionFactors that will influence the property of crystallization result include temperature air pressure distilling time and others.

Crystallization is a natural process which happens when the materials solidify from a liquid or as they precipitate out of a liquid or gasThis process can be carried out by causing a physical change like a change in temperature or a chemical change like acidityThe crystallization process is carried out on the basis of the size and shapes.

Crystallization is often a critical processing step in the isolation of intermediates and final product.
