WebThe rate of crystallization should not exceed values that cause too much uptake of solvent via inclusions. For a cooling crystallization, natural cooling profiles should be avoided, as most of the material crystallizes too fast. Linear cooling rates are a first approximation. The rates can be classified as slow, realistic, fast and crash ...
