Crystallization - Wikipedia

Crystallization or crystallisation is the process by which a solid forms, where the atoms or molecules are highly organized into a structure known as a crystal. Some of the ways by which crystals form are precipitating from a solution, freezing, or more rarely deposition directly from a gas. Attributes of the resulting crystal depend largely on

Differences between crystallisation and evaporation to dryness

17/1/2021· 2. Difference in heating: crystallisation involves less heating. Evaporation to dryness is the more brainless method. We simply heat the solution until all the water boils off. This will leave behind the solid product and you are done! In contrast, crystallisation is a delie method involving careful heating to remove some water.
