What is powder?

A collection of an extremely large number of solid particles, in which appropriate interaction forces are acting between each particle.

A powder is defined as "an extremely large collection of solid particles, in which appropriate interaction forces are acting between each particle." This is a qualitative definition, so there are quite vague points, but in short, it refers to what we visually perceive as powder and behaves like powder. The greatest feature of powder measurement is that it measures a collection of fine particles. In the case of particle size measurement, it is rare for all the measured fine particles to be of the same size. Most are collections of particles of varying sizes, more or less. To measure this and accurately represent it, it is necessary to statistically process the particles as a collection and express what sizes of particles exist in what proportions. *For more details, please refer to the related links or feel free to contact us.*
