Orsakerna till den spontana förbränningen av nanojärnpulver i luft

Nano iron powder possesses an extensive surface area, resulting in an exceedingly fast oxidation rate on the surface. This leads to rapid heat accumulation that cannot be dissipated efficiently.

The generated heat further speeds up the surface oxidation process. This ongoing accumulation of heat eventually allows the järnpulver to ignite spontaneously in the air.
