Particle-size distribution - Wikipedia
The particle-size 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 stone size distribution.

Particle size - Wikipedia
Particle size is a notion introduced for comparing dimensions of solid particles (flecks), liquid particles (), or gaseous particles ().The notion of particle size applies to colloidal particles, particles in ecology, particles present in granular material (whether airborne or not), and particles that form a granular material (see also stone size

PARTICLE SIZES EXPLAINED
Well, it can definitely help you to know how the particle "size" ratings get assigned to metal powders. Most of the size ratings come directly from the wholesaler or manufacturer. But every so often we buy surplus materials which may not come with any additional information about the manufacturer, the size or shape of the powder.
