WebIn a free- flowing powder, such interactions are less significant, and Apparatus and Procedure—Proceed as directed under the bulk and tapped densities will be closer in value. A powder is called free-flowing if the particles do not stick together. If particles are cohesive, they cling to one another to form aggregates. The significance of cohesion increases with decreasing size of the powder particles; particles smaller than 100 µm are generally cohesive. See more A powder is an assembly of dry particles dispersed in air. If two different powders are mixed perfectly, theoretically, three types of powder mixtures can be obtained: the random mixture, the ordered mixture or the interactive … See more The term ordered mixture was first introduced to describe a completely homogeneous mixture where the two components adhere to each other to form ordered units.
