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 ... WebSep 18, 2024 · For polymers and pharmaceuticals, the determination of the crystalline fraction by DSC measurement is accepted across the whole world [54, 55]. In the case of a sample with nanocrystallites in the amorphous matrix, the volume fraction can be estimated by using the following relationship [56, 57]:
WebThe integrated intensity from a diffraction peak is proportional to the volume fraction of that material in a sample. This means that for a material with multiple phases, crystalline/amorphous or several crystalline phases, XRD can be used to determine the volume fraction of these phases.
