In the "terrorist's cookbook", as it was known to me (not that faggot annarchist ripoff one) near the end there is a section entitled: "Useful Pyrochemistry"
And it had a set of equations for making Al powder from foil, HCl, and Magnesium.
here it is:
Quote:
5. powdered aluminum from acids, aluminum foil, and magnesium
A. aluminum foil + 6HCl ----> 2AlCl + 3H
3 2
B. 2AlCl (aq) + 3Mg ----> 3MgCl (aq) + 2Al
3 2
The Al will be a very fine silvery powder at the bottom of the container
which must be filtered and dried. This same method works with nitric and
sulfuric acids, but these acids are too valuable in the production of high
explosives to use for such a purpose, unless they are available in great excess.

So yeah, i've been wondering about this for the last week and I decided to ask you beasts about it.
I remember fucking around making loud noises with Al foil and HCl in plastic PET bottles, but from memory there was left over Al. (Al-foil reacts fairly violently with HCl giving off H2 gas in vast amounts... in case anyone has been living under some chemitry devoid rock or some shit)
If i get some HCl (a good couple of litres) and dissolve as much Aluminium foil in it as i can (until the solution doesn't fizz with the addition of more foil) do you think adding some Magnesium to the Aluminium Chloride will do anything??
If so, will it leave nice pure Aluminium like this old text says? (its a bit dodgy in parts, but far better than the annarchist cookbook)
If so then I'll make some flash powder with some Potassium Permanganate. Equal parts seemed to do fine back in the day.....
