Abstract
Ignition of Fe nanopowders of bulk density and its samples compacted to relative density of 0,3-0,5 was studied while they were heated in the air. The ignition temperature of the compacted samples does not depend on the heating rate and comprises 100-115 °C. The oxidation process includes the stages of inert heating, ignition, surface and filtration modes of the reaction and afterburning. The time of the active stages, i.e. ignition and filtration mode, depends on the sample density at the same heating terms. It allows one to develop storage methods of Fe nanopowders as compacts.
