3. Dimensional measurements
For more information on the methods used, please refer to the specialized articles in the Analyse et Caractérisation dans les Techniques de l'Ingénieur documentary database.
Any dimensional measurement requires a definition. This is straightforward for particles with simple geometries (such as spheres, cubes, etc.), but problematic for particles with complex shapes, such as non-convex polyhedra or branched particles. These measurements can be used to monitor plant operation or the quality of fragmented products.
A particle has given physical dimensions, and a population of particles is described by their distribution, which has very different meanings depending on whether it is weighted by number, mass or surface area. A narrow distribution is said to be monodisperse; otherwise, it is...
