crystallization
Crystallization refers to the process of coagulating from a saturated solution, or a solid (crystal) with a certain geometrical shape from the gas condensate. In the natural environment, the temperature drop the role of pressure, will cause crystallization. The crystallization process can be divided into two stages (including nucleation and crystal growth), and the time is different. Crystallization is also a technique for separating solid and liquid substances in which solutes are transferred from the solution to pure crystals. Many natural processes involve crystallization: ▪ the formation of natural crystals (such as minerals, precious stones, etc.) ▪ the formation of snowflakes ▪ The crystallization of honey, such as the slowness of the saturated solution, slows down to form a larger crystal; , Will form a small crystal powder. While small crystals can be placed in saturated solutions to act as large crystals of seeds. And recrystallization or recrystallization is repeated crystallization, to prepare the higher purity of the crystal. ...
