dry ball milling process of aluminum flake powder

Reaction of Aluminum with Water to Produce Hydrogen

It has been speculated that the milling of aluminum and aluminum oxide powders together helps to mechanically disrupt the adherent and coherent oxide layers present on the aluminum powder, and that this is the reason for the enhanced hydrogen generation in pH neutral water (11-13).
