What iron oxide is better for thermite? (red or black) What is the fastest way to make them?

Black oxides sometimes have water in them, and are not as oxygen rich as red oxide, so
the red one is better.

There are a kind of "warm pouch" for sell in
pharmacies, you open it, shake a little, then
it starts to warm up, that's for use in winter. It is mainly iron powder, plus water,
and some electrolyte, maybe calcium hydroxide.

Use more water to wash away electrolyte (here's a tip, place a magnet outside the beaker to help iron stay at bottom, no filters needed), then heat the powder with strong heat, stir them so they don't block,
the heat can both vaporize water and oxidize
the iron, when you see the powder is turning
red, heat some more, and you are done.

Take a very strong magnet inside of a plastic bag and run it over dry dirt or sand (river or ocean). There's plenty of iron oxide in dirt, free for the taking.

Hey everybody, I havent been online in a few days. Regarding the post, when I was younger I used to take a big magnet to the park and a plastic bag. I'd run the magnet over the sand(sand boxes around playground equipment etc..) then when there was too much on the magnet I would remove it by scraping it into the bag. I got several hundred grams of iron fillings doing this is a relatively short period of time. Another way would be to wet some steel wool and leave it in a plastic container for a while, works nicely.

This is sort of a long and difficult way to make iron oxide but it sould be worth the trouble if large amount of iron oxide is to be made.

Boil up iron metal(steel wool) in a acid(HCL)
Use exess metal so that all the acid will be used and then remove the exess metal.
Now add sodiun hydroxide solution. This will make iron hydroxide presipatate. Now the hard part is to filter the iron hydroxide( facuum would be nice. Heat this inside a metal pipe in a very hot fire (RED hot) for 1hour + and the hydroxide will decompose to the oxide.

Heres a file i found on the web.

Iron (III) Oxide the EASY way.
So you've read the anarchists cookbook on making thermite, you want
iron (III) oxide but don't want to run the risk of shorting out the
electricity in your entire house, while at the same time electrocuting
yourself while choking to death on chlorine fumes. Let's face it
getting Iron (III) oxide with electrolysis is dangerous, takes ages
(I had it hooked up for a few days in my garage and got less than an
eighth of a gram of rust), and if you don't have an AC to DC converter
your fucked.
You want a good chemical method for extracting Iron from stuff
containing iron.

You will need:
2 glass jars
funnel
filter paper
ammonia or caustic soda (sodium hydroxide)
water
Iron sulphate tablets (or anything else containing iron)

1) Add some ammonia or caustic soda to a jar containing water, the
ammount isn't important (you don't need much water if your using
ammonia).

2) Get your Iron sulphate tablets and crush them up

3) Add the tablets to the other jar and add just enough water to
dissolve them. You may want to use a lot of tablets, or just go
down to your local garden center and pick up a big box of gardening
fertiliser stuff (must contain iron) and use that. Once again the
ammount of water isn't important, just dissolve as much as you can
in a bucket and scoop out the solution as you need it.

4) Tip the contents of jar 2 into jar 1, now stir.

What do you see? green shit in the jar. The green stuff is Iron
Hydroxide, now for those of you doing either A-level chemistry or GNVQ
science, I will point out that iron hydroxide is unstable as it is
lacking a third oxygen molecule, hence it is Iron (II) Oxide.

5) Filter the green stuff out, use jar 2 to filter the liquid into.
Save the green stuff.
(beyond this the steps are optional)
6) Add more water to jar 1, then add the green stuff, now stir.

7) Filter out the green stuff (should be turning brown)

8) Leave to dry, by the time it has dried it will have turned brown/red
in colour. This is pure Iron (III) Oxide, and it's as fine as flour.

Now wasn't that method much more simpler and quicker than hooking up
all of the stuff that you would need if you did it the other way.

If you want to do this on a mass scale, simply do the following:
Get two buckets, a bottle of ammonia and a large box of fertiliser
stuff (containg iron).

1) Tip the fertiliser stuff into the first bucket, with some water to
dissolve it all.

2) Tip the ammonia into the second bucket.

3) Tip the first buck into the second bucket and stir

4) Filter and save the green shit. (Will oxidise compleatly in a few
minutes).

Carrying out either of these methods takes less than five minutes to
do, I have yet to try and dump a load of nails into the ammonia. In
theory it should work and would produce the greatest ammount of iron
(III) oxide.

Hope this helps

Thanks guys, im going to try the ammonia method, as soon as I get to the store.

I was at the hardware store today and saw a 5 pound bag of Iron Sulfate on sale for $5. The bag says it has a 19% Iron content (as Fe). At that rate, a pound of iron oxide should cost about $5.
