Flow characteristics of powder
WebPowder flow EUROPEAN PHARMACOPOEIA 6.0 since the lattice parameters are comparatively large, the symmetry is low and the scattering properties are normally ... WebMany powders have particles of small size and irregular shape. They are cohesive and do not flow well. Granulation leads to larger more homogenous particles with better flow characteristics, improving the tablet making process. Compacted granules occupy less volume/unit weight compared with powder and is easier to store and ship.
