Just doing a search, here is an article discussing hydrogen permeation of
Alumina at high temperatures.
http://www.academia.edu/7323157/GAS_PERMEATION_PROPERTIES_OF_HYDROGEN_PERMEABLE_MACROPOROUS_ALUMINA_CERAMIC_MEMBRANES_AT_HIGH_TEMPERATURE

Of course this is about porous alumina membranes to purify hydrogen, but
the effects of high temperature may apply to alumina in general porous or
non-porous.
