WebA very important feature of a metal is the average size of the grain. The size of the grain determines the properties of the metal. For example, … The notion of particle size applies to particles in colloids, in ecology, in granular material (whether airborne or not), and to particles that form a granular material (see also grain size). Measurement [ edit ] See more Particle size is a notion introduced for comparing dimensions of solid particles (flecks), liquid particles (droplets), or gaseous particles (bubbles). The notion of particle size applies to particles in colloids, in See more There is an international standard on presenting various characteristic particle sizes, the ISO 9276 (Representation of results of particle size analysis). This set of various average sizes includes median size, geometric mean size, average size. In the selection of … See more There are several methods for measuring particle size and particle size distribution. Some of them are based on light, other on ultrasound, or electric field, or gravity, or centrifugation. … See more • Dynamic light scattering • Laser diffraction analysis • Micromeritics See more
