Abstract

A powder is a solid state fine dry bulk, composed of particle of varying shape, grain size, and flow properties. Despite the desirable properties of being in fine size, but it has manufacturing limitations such as difficulty in flowing and clumping together. Therefore, the granular course size is preferred to overcome such problems in manufacturing technologies. Powders have different classifications and different uses according to the route of administrations which will be covered in this review.
