There are at least three standard thermate compositions in US military use, I believe they are designated TH1, TH2 and TH3.
I don't recall the compositions from my skull but I guess they can be found in PATR 2700 (Federoff's Encyclopedia of Explosives & Related Items)
from US Army Picatinny Arsenal. This is available from MadHayyer FTP.
If you want to download this, from experience I can tell you, get the single zip file as some of the 1-file sets have individual files that are
corrupted. Very frustrating to download 650 Mb and find that one of the volumes won't decompress.
PS: is Pyrotherm still classified or is this in the open lit yet?
It's a closely related composition.

That is the TH3 composition, according to wiki. I'll look up that book.

You will want page T-189 of Volume 9 of PATR 2700
They give only the TH3 composition, but say it is best of the lot. And that the main use of the thermates is as igniters for magnesium incendiary
bombs (the bomb casing itself is magnesium and is the actual main incendiary..
Er, you live in a dorm, so let's be sure you appreciate that you must not test this in the dorm...right?
I knew a fellow who tested thermite in his back yard and he melted a hole in a cement flagstone and singed off his eyebrows. FWIIW thermate
compositions containing sulfur are designed to scatter on ignition. Like the Chinese fireworks say, light fuse, retire quickly!
If you are going to do this on campus, if I were you I would seek permission, and if that is not forthcoming move your experiment off campus to
someplace safe and private.

That's exactly what I wanted to know. If it's designed to explode or expand to a large area in some way, it's not for me, at least not around this
area. I'll stick with regular thermite for now.

Just remember it's molten iron we are talking about, 2500 C, 705 Kcal/gram released and the white hot iron and alumina slag will stay hot for some
time.
The military use thermite and thermate grenades to destroy critical equipment so that it does not fall into enemy hands. Crypto equipment, heavy
weapons, sniper rifles etc. get the treatment at bug-out time.

If I just added the barium nitrate and left out the sulfur, would it still explode? I've read that the barium nitrate is used to lower the ignition
temperature, and it also increases the thermal effects.

It should be fine.
I still have that fused spot on the sidewalk where I lit off a pile of Ba(NO3)2 and MgAl...

I wouldn't say "explode" but the sulfur scatters it a bit.
I don't think you need the Ba nitrate, straight thermite is dramatic enough.
There are many other thermite mixtures besides iron oxide/Al.

A bit off topic, perhaps, but speaking of dramatic effects of thermite, just take a look at the WTC 1 & 2 colapses. In one video sequence, you can
actually see the molten iron pouring out of one of the windows. Though the latest research on the topic states that it was thermate used, not regular
thermite.
Also, speaking of the fact that the molten iron produced in the thermite reaction stays hot for some time... In the rubble at ground zero, i.e. where
WTC used to stand, in the basement they (those who helped rid the evidence from the crime scene) found pools of red to yellow hot molten iron no less
than FIVE days after the collapse of the buildings.

I have read about a few other mixtures but I have not been able to find specifics on composition. I've heard of Mg/teflon and a few others. Which
would burn the hottest, and which would give the most dramatic display in terms of brightness?

I'm aware of the whole debate on that, and I'd rather not start up a political discussion, since
it's considered a conspiracy theory.

Here's something that will enlighten.
I am removing this attachment as it is rather large and so anyone who did not download it in time (15 did) pls fetch it from FTP MadHatter site.
It'll be in the UPLOAD/Sauron folder

I don't hate Muslims and I still file WTC thermite/thermate in the "retarded conspiracy theories" bin. I'm sorry I didn't see this thread in time to
save it. Anyone who wants to advance or debunk WTC controlled demolition will do it in Whimsy from this post forward. Any further posts in this thread
advancing the theory, or even attempting to counter it, will be removed and may earn the poster a temporary ban on posting.
Furch, or anyone else who's considering it, please do not enter threads on scientific/technical topics in the main forums and then
derail them into political or ideological topics.
Edit: the Whimsy thread has been started here, beginning with unionised's next post from this thread.

You need to PM MadHatter (the member here) and request access to the FTP site. You will need a good FTP client application.
MadHatter will (eventually, be patient) send you address details and user name/password. It's his private site, it does not belong to the forum and so
access is a privilege and not a right.
Did you download the Sandia combustible metals file I uploaded above, while it was up overnight? It was you I put it up for. It was over 1 Mb and the
forum upload limit is finite, so I did not want to leave it too long.

OK, attachment is gone again. I suggest you take a minute and delete the posts concerning this (at least three of them) as they are now meaningless
and clutter up the thread. Once you do I can delete this one as well.
