So I recently found very fine aluminium powder and Chrome Green (chromium oxide) paint pigments in a friend's art stash. I figured these could be used in a Thermite reaction, since I'm pretty sure Chrome Green is fairly pure chromium (III) oxide. The only tutorials online, however, are for iron oxide thermite, and the red pigments my friend has are all synthetic iron oxide, so they aren't the actual substance, so chromium oxide is the only metal oxide we have. Basically, I guess the only thing we need to know is the proportions to mix them in. I read that for aluminium and iron oxide it's 8 grams to 3 grams, but does anyone know what we should use for aluminium and chromium oxide? I couldn't find it after Googling. Thanks in advance.
