The fine particles to which any dry substance is reduced by pounding, grinding, or triturating, or into which it falls by decay; dust.
To reduce to fine particles; to pound, grind, or rub into a powder; to comminute; to pulverize; to triturate.
Finely divided solid; particles are smaller than one millimeter in maximum dimension. It is metallic, ceramic or a polymer; these can be blended in infinite combinations. An important characteristic is the relatively high surface-to-volume ratio of the particles which exhibit behavior that is intermediate between that of a solid and a liquid. Powders will flow under gravity to fill containers or die cavities, so in this sense behave like liquids. They are compressible like gas. Powders are easily shaped, with the desirable behavior of a solid after processing.
Fine powder used on during the printing process to prevent offsetting.
An explosive mixture used in gunnery, blasting, etc.; gunpowder. See Gunpowder.
