Hi,
I will ask a naive question to competent people here.
As Jack Cole have shown LiAlH4 seems not required, but anyway Rossi is using it in his alumina Al2O3 reactor...
One problem of the reactors is H leakage.
then I connected all of that and got an idea ... I noticed that Alumina and LAH contain aluminium, and air and alumina contains oxygen.
when there is a leakage in the tube because alumina is not perfectly tight, some Al may be pushed in the cracks, and will meet some O2 from air... maybe becoming alumina at high temperature... thus closing the cracks.
maybe is that a self-healing material ? a tricks of rossi to solve his problems with leaks?
One day he referred to an "illumination" about a simple idea top solve a big problem... If it works I would feel so.
does it looks realist ? is it a known phenomenon ?
Of course this reaction would compete with others, and not sure it is dominant compared to H2+O, or others... I cannot judge if it is realistic.
moreover the dominant reaction may change with temperature and pressure.
