Your thorough examination of thermite that has been brought up numerous times makes me apt to come to you for some discussion/answers. I've seen all the mentioned iron oxide making processes, but I have yet another I'd like checked and thought through. What if I did the following... acid steel wool a salt... hydrogen gas? 2HCl + Fe --> FeCl2 + H2(g) and then after dissolving all of the iron in the HCl, I'd do this with some quite impure Sodium Hydroxide. (The purity of NaOH shouldn't matter, since I can wash the iron oxide in water or alcohol.) FeCl2 + 2NaOH --> Fe(OH)2 + 2NaCl To get rid of the NaCl, all I'd have to do is wash the precipitate. I realize that I still have Iron Hydroxide, not Iron Oxide. In theory, wouldn't that actually WANT to oxidize further with ambient air to form Fe2O3? If so, great. There's an easy and fast way to make one of my reactants, if it will work. I do have one more question. I have have some VERY pure aluminum flake. It's about -20+30 mesh or so. Seems like that would be too coarse for a thermite reaction. I haven't tried it yet, but I know that I've never seen aluminum this coarse used in an aluminoferrite reaction. Can anyone think of a way to use it for this reaction? I have exactly one pound of it.
