Crystallization - shoseki (English spelling) crystallization
Crystallization is the process of precipitating components contained in a solution as crystals. Crystallization is generally considered to consist of two processes: the generation of crystal seeds or nuclei and growth from the seeds. The driving force in the growth process is the degree of supersaturation of the solution, which governs the growth rate. The purpose of crystallization is usually purification and granulation, and the equipment that performs crystallization is called a crystallizer. Supersaturated solutions can be created by evaporation or cooling.

Japanese:
溶液からその中に含まれている成分を結晶として析出する操作をいう。晶析現象は,一般に,結晶の種あるいは核の生成と種からの成長の2つの過程から成ると解釈されている。成長過程は溶液の過飽和度が推進力となり,それによって成長速度が支配される。晶析の目的は通常精製と造粒であり,晶析を行う装置を晶析器という。過飽和溶液をつくるには蒸発によるものと冷却によるものとがある。
