Quick explanation of thermite:

A mixture of iron oxide Fe2O3 (rust) and aluminum powder. When it is ignited the aluminum powder reacts with the O3 part of the rust in a highly exothermic reaction, the resulting product is molten iron.

Thermite is commonly used in welding, because the molten iron has the ability to seep into cracks in metal. It cal also be used to melt through things as shown in an episode of Brainiac and the movie The Sixth Day.

I have made thermite a few times, but never in large enough batches to burn through anything significant. Aluminum powder is hard to come by and I never had a good enough reason to use what little powder I had.

Step 1: Materials

All materials can be found here http://unitednuclear.com/chem.htm or on E-bay. You can either buy and mix the chemicals yourself or buy premade thermite from unitednuclear.

1. Iron oxide
2. Aluminum powder
3. Magnesium ribbon or thermite ignition mixture

For a more exotic mix you may also want to buy:

4. Barium Nitrate
5. Sulfur
6. Dextrin
<p>does anyone here because breaking bad ? </p>
oh yes.
<p>Need Aluminum Powder but the Mad-Science shoppe is closed? <br></p>
<p>Sorry, but that Breaking Bad episode where Heisenberg makes thermite from the contents of an Etch-A-Sketch and then uses it to burn through a lock was conclusively debunked by Thunderf00t on Youtube. You don't don't need an Etch-a-Sketch anyway. Just get the stuff from Ebay. </p>
<p>and you are the kind of person that would die if they ever tried to make meth</p>
sorry to be a smart arse, but the percentages of the mix add up to more than 100%. if you mix 76.3% iron oxide with 27.3% aluminum powder, then you get 103.6% thermite. this doesnt make sense to me, so could you explain it a little please. thanks
<p>It doesn't make sense because it's 76.3 : 23.7 (NOT 27.3)</p>
I saw that too!
Were you directed here by one of mythbusters episodes with thermite? I was!
believe it or not, no. Ive never watched mythbusters
I love the ice thing! Ive seen almost every episode! Wensdays at 9!
In Eastern stations it used to be, but now its at 8 for some reason. I hear the next myth is on Golf Balls and if the dimples affect flight. it was in a Pop Mech article about the Mythbusters.
I was too
He switched the 7 and the 3 in the aluminum powder percentage. It should read "76.3% Iron Oxide" and "23.7% Aluminum Powder."
at last...it makes sense. thanks
he just wants to get fancy-ish woth that. mix 75 and 25. also, you can do aluminium powder grinding or blending aluminium paper!
how would you recomend getting the alunimum powder and the iron stuff?
now, how to you mix 76.3% with 27.3% of anything? Is 100% not a limitation here? please explain how to get 103.3%<br />
<p>76.3% to 23.7% (NOT 27.3%)</p>
Anywhere between 3-1 to 3-2 ratio will work, just play around with it a little.<br />

<p>What if you mixed the Thermate with magnesium powder? Is that stable? The U.S. Army manual 'Improvised Munitions' instructs to mix magnesium powder with potassium permanganate for storage in a tightly sealed container. Maybe magnesium and potassium permanganate powders can be mixed with Thermate. A match or glycerin would ignite the potassium permanganate, and even the magnesium. Then the whole batch is ignited.</p>
<p>What if I rolled cotton string in a mixture of black powder and magnesium powder, and maybe potassium permanganate too? I read that the military stores magnesium mixed with potassium permanganate. I don't know if either would be stable mixed with black powder. I'm trying to figure this out myself. I think a mixture of at least two of the three would work. I would then run the string through a small vial of clear nail polish to make it waterproof. What do you think?</p>
<p>Using black iron oxide Fe2O3 and and Al (3Fe3O4 + 8Al --&gt; 9Fe + 4Al2O3 + heat) it's 76.3% iron oxide, and 23.7% al by weight</p>
<p>Using RED iron oxide (Fe2O3+2Al --&gt;2Fe+Al2O3+heat) it's 74.7% iron oxide, and 25.3% al by weight</p>
<p>103.6%?</p>
<p>Using black iron oxide Fe2O3 and and Al (3Fe3O4 + 8Al --&gt; 9Fe + 4Al2O3 + heat) it's 76.3% iron oxide, and 23.7% al by weight</p>
I don't really know much about thermite. What is the difference between the military version and the regular version?
<p>Military version ignites easier, and spreads easier with more outgassing.</p>
<p>How hot it burns. The military version burns hotter and faster. </p>
<p>It comes from a chemical supplier like US Halogens to get the best results. Some aluminum and iron oxide you find online give you crumby yields. Try a reputable company like www.americanelements.com or www.ushalogens.com check the products or merchandise pages. Here's a bar with slag we made from their aluminum powder / copper oxide mix</p>

<p>You can also use sparks from ferrocerium 'flints' to ignite thermite. It's a bit tricky trying to aim the resulting sparks into the thermite mixture but a good substitute if you don't have any magnesium or sparklers.</p>

instead of iron oxide powder u can use copper powder for a explosive mixture
<p>is it possible to convert this to units by weight? thanks guys happy burning :)</p>
Well getting any sort of fuse is literally impossible for me. Neither can I make my own. So just wondering... could I take apart my kettle and use that heating element instead? I don't suppose there is any sort of limit to that is there?
you can light Thermite with about 4-8 sparklers wrapped together then stick it in and light it.
you would be covered in 3rd degree burns. You wouldn't have enough time to get away, and do you have any idea how hot thermite burns?<br />
i don't know what sparklers you have, where I'm from they are about 20-30 cm they take about 30 seconds to get to the bottom and that is a good amount of time to run away<br />
<strong>spark</strong>lers make <strong>sparks</strong>, and when those sparks hit thermite, it burns. <br /> <br /> P. S. here they take about 45 seconds to 1:15 here to burn.<br />
but Thermite is int highly sensitive and would take more than a spark
The sparks are not hot enough, and if they are they I consider the unlucky candidate the most unlucky candidate ever.
&nbsp;about 2000 degrees of the top of my head, but I forget things easily, all I know is it makes light work of an old sky box and the pot used to hold it together
kind of a rhetorical question, but thanks anyway.<br />
you could just short out a battery (attach one piece of wire to both contacts)
