Once a critical nucleus … WebFeb 2, 2011 · The bulk (typically > 90%) of the solution or melt forms crystals either in suspension or on a cooled surface. Impurities remain in the small amount of uncrystallized mother liquor. Melt crystallizers forming large high-purity single crystals. Crystals form very slowly from high-purity melts, yielding large, pure and defect-free crystals.
WebJan 29, 2024 · Crystal growth after nucleation is typically affected by defects that limit crystal size. Various seeding techniques can be applied to overcome the nucleation bottleneck. The basis of crystallography is that a crystal is a nearly perfect periodic three-dimensional arrangement of molecules (the ‘lattice’).
