The Conditions for Spontaneous Combustion of Aluminum Powder

The self-ignition of aluminum powder is linked to moisture and steam in the environment.

aluminum powder
As a powder, aluminum’s surface activity is heightened, leading to a reaction with water that generates heat and hydrogen gas. Should this hydrogen gas accumulate to a specific threshold, spontaneous combustion can occur. Subsequent to combustion, relighting aluminum powder with oxygen leads to an even more vigorous exothermic reaction at elevated temperatures.
