- Solids exist either in amorphous form or in crystalline form.

- polymorphism When a compound crystallizes from a solution or slurry, it can crystallize in different spatial lattice arrangements (this property is called "polymorphism") to form crystals with different crystalline forms.
- These various crystalline forms are Called "polymorphs". Different polymorphs of a given substance may differ from each other in one or more physical properties (such as solubility and dissolution rate, true specific gravity, crystal shape, packing method, fluidity, and/or solid state stability).
- the "crystallization” can be achieved by manipulating the solution so that the solubility limit of the compound of interest is exceeded, thereby completing production-scale crystallization. This can be done in a variety of ways, for example, dissolving the compound at a relatively high temperature, and then cooling the solution below the saturation limit, or reducing the liquid volume by boiling, atmospheric evaporation, vacuum drying or some other method. Alternatively, the solubility of the compound of interest can be reduced by adding an antisolvent or a solvent in which the compound has low solubility, or a mixture of such solvents. Another alternative is to adjust the pH to reduce solubility.

Similarly, in a medium with less solubility than the reactants in the final desired form, the completion of the synthesis reaction can directly crystallize the final product.
- the optimization of crystallization may include seeding the crystallization medium with crystals of the desired form as seeds.
- many crystallization methods use a combination of the above strategies.
- One example is to dissolve the compound of interest in a solvent at high temperature, and then add an appropriate volume of anti-solvent in a controlled manner so that the system is just below the saturation level. At this time, a desired form of seed crystal can be added (and the integrity of the seed crystal can be maintained), and the system can be cooled to complete crystallization.
