  • Powder particles average characteristics

    Powder cohesivity depends on its interparticle forces and particles weight [20] Fine powders tend to agglomerate given their inherent strong interparticles attractive forces compared to coarse powders [14, 21] The flowability of used powder [22] may43 When an “average” particle size of powders is determined by these methods, it should be clearly kept in mind that this average size is derived from the determination of the specific surface area of the powder using a relationship that is true only for powders of uniform size and spherical shapeStandard Test Methods for Estimating Average Particle Size

  • Particlesize distribution

    The particlesize distribution (PSD) of a powder, or granular material, or particles dispersed in fluid, is a list of values or a mathematical function that defines the relative amount, typically by mass, of particles present according to size Significant energy is usually required to disintegrate soil, etc particles into the PSD that is then called a grain size distribution– Nonthermodynamic (average KE of particles » k BT) systems, in other words there is no welldefined granular “temperature” – corollary: most properties of interest are not a function of state (beware!) and therefore powders are highly processsensitiveEffect of particle size and shape on powder properties
