WebOiling out in crystallization is a process in which supersaturation causes the initially dissolved compound to separate from solution by creating a secondary liquid phase (emulsion) (image 1a) instead of a solid, crystalline phase (suspension) (image 1c). Oiling out mostly occurs when the integration of solute molecules into the crystal lattice is … Crystallization is the process by which solid forms, where the atoms or molecules are highly organized into a structure known as a crystal. Some 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 factors such as temperature, air pressure, and in the case of liquid crystals, time of fluid
