Is aluminum oxide combined with iron oxide reactive thermite?

Recommended Posts

I want to make some aluminum powder to use in thermite, I've seen people in youtube making it from  powdered aluminum foil. I was wondering if i can make aluminum powder by grinding aluminum beams from windows/doors or aluminum cans using angle grinder (disc cutter). . I heard that if you mix the aluminum powder with a little charcoal it will keep it from oxydising? I Can i remove the O from the aluminum with some chemical?s aluminum oxide combined with iron oxide reactive thermite?

No.

Aluminium is capable of extracting oxygen from carbon dioxide (in much the same way that it removes the oxygen from iron oxide).
