Nonetheless, a different class of powders has arisen in the last few yrs that could be uniformly fluidized within a nonbubbling fluid-like condition. Fine particles in these Specific powders aggregate according to the dynamic aggregation course of action, which winds up While using the formation of porous light-weight aggregates which can be fluidized by a fuel, very like coarse beads are fluidized by a liquid. On this chapter, the classical Geldart diagram as well as newly-described fluid-like habits exhibited by this Distinctive course of fine powders are reviewed.
A drinking water-soluble drug contained in an oral powder dissolves a lot more speedily than the same drug contained inside a tablet or capsule, where the tablet or capsule shell have to be disintegrated right before dissolution.

The move of powders in individual ways of additive technologies is a posh place of examine. Powder firms want to keep away from flow troubles including segregation, vaulting, agglomeration, and want to predict how a particular steel powder will flow and variety/not variety a homogeneous layer, or Evaluate the movement qualities of metallic powders with each other.
