Re: aluminum oxide

As Don Keeney said; "it acts as an inert ingredient in end plug mixtures". 
Al2O3 is already as oxidized as Aluminum gets so the only thing it will do

in any pyrotechnic mixture is slow down the burn rate by getting between 
other active fuel or oxidizer particles. It is, for all practical
purposes, 
an inert material. The best use for Al2O3 is as either a pre-polish or
final 
poli****ng compound for lapidary work or in larger particle sizes as an 
abrasive coating on sanding papers/cloths. It is a very hard material with
a 
Moh's hardness of 9.

 Another poster mentioned the Hall process. As you can see, the best place

for your Al2O3 is, right where you found it.
