Step 2: Mix

Mix 76.3% iron oxide with 27.3% aluminum powder to make thermite.


To make the military version Thermate create a mixture of 68.7% thermite, 29.0% barium nitrate, sulfur 2.0%, and dextrin 0.3%.

<p>is it radioactive?</p>
<p>no it isnt</p>
<p>I use this to burn stumps, and it entertains the children. x &gt;</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
I saw that too!
Were you directed here by one of mythbusters episodes with thermite? I was!
I was too
Cowboy does this really work
Hi
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.
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?
<p>Amazon</p>
<p>It doesn't make sense because it's 76.3 : 23.7 (NOT 27.3)</p>
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
<p>The debate over Fe2O3 to AL ratio is 80:27... both materials are available though Amazon or Ebay. Other sites offer the materials by the tonne...The ration is by weight. I am mixing 800 grams to 270 grams.</p><p>I'm using a 3 inch &quot;fuse&quot; of magnesium in my first attempt... had to get a torch (as in a burning torch) to ignite the fuse. Once I go with that I will also attempt using nichrome wire off a lantern battery, a fireworks igniter off a lantern battery and a final test of potassium permanganate with glycerin. Once I verify the ignition system that works best (safest) I'll add the thermate materials to the mix and update.<br>For a &quot;hotter&quot; burn I've read that using CuO2 or other oxidizers is better than Fe2O3. Also using different more reactive metals in theory makes it hotter but getting too reactive make storage unstable both from a reactive view and shelf life.</p>

<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>
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 />
3:1 iron oxide to aluminum by weight<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>
<p>If you like this you should check out Thermite Arts on <a href="https://www.etsy.com/shop/ThermiteArts" rel="nofollow">kickstarter</a> and on <a href="https://www.etsy.com/shop/ThermiteArts" rel="nofollow">etsy</a>. They have thermite kits on etsy.</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?
