In powdered form, activated carbon is extremely fine, with an average particle size of only 20 microns and a bulk density of lb/cu ft ( kg/cu m). It is extremely aeratable, meaning the slightest air movement may cause the activated carbon powder to take flight and settle as dust. This dust fluidizes, or takes on the properties of a liquid.
