The feedstock for crystallisation is a solution with crystallisable ingredients, e.g. minerals or organic molecules. The majority of minerals and organic molecules | The feedstock for crystallisation is a solution with crystallisable ingredients, e.g. minerals or organic molecules. The majority of minerals and organic molecules crystallise easily, and the resulting crystals are generally of good quality, i.e. without visible defects. However, larger biochemical particles, like proteins, are often difficult to crystallize. The ease with which molecules will crystallize strongly depends on the intensity of either atomic forces (in the case of mineral substances), intermolecular forces (organic and biochemical substances) or intramolecular forces (biochemical substances). | ||
