Reaction of Aluminum with Water to Produce Hydrogen
www1.eere.energy.govThe aluminum oxide may be in the form of bayerite (Al(OH) 3), boehmite (AlO(OH)), gamma alumina (γ-Al. 2. O. 3), or alpha alumina (α-Al. 2. O. 3). Alpha alumina powder was reported to give the ... which would grow in thickness until the boehmite reacted with the underlying aluminum to produce hydrogen bubbles at the aluminum-boehmite ...

materialsdata.nist.govan inert aluminum oxide film only a few ten-millionths of an inch thick, which blocks further oxidation. And, unlike iron rust, the aluminum oxide film does not flake off to expose a fresh surface to further oxidation. If the protective layer of aluminum is scratched, it will instantly reseal itself.
