Different powder types. 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.. Random mixture. A random mixture can be obtained if two different free-flowing powders ...
K.G. Ewsuk, in Encyclopedia of Materials: Science and Technology, 2001 (a) Powder flow. Typically, powder flow is characterized by the time it takes a given mass of powder to flow through a given size of funnel. Powder flow also can be assessed by the angle of repose that a loose powder makes when poured onto a flat surface (i.e., the angle measured between the flat surface and the cone ...
