View Full Version : Does "nano-thermite" actually exist?

I've been shown a couple of sources to prove that there is something that has been researched matching the general description of nano-thermite, but I still haven't seen it in action.
Does it exist? Has it been demonstrated? Can it cut steel columns quickly and quietly?

Not in the context that CT'ers claim it does.
Thermite's existed for a long time. Thermite grenades were used to permanently foul the firing chambers of German artillery pieces during WWII, for example.
And no-it couldn't have cut the weight-bearing structures of the Twin Towers quickly or quietly. It would have taken a few minutes, IMHO. People would have noticed it, and it would have been visible from outside the building. Plus - it doesn't explode.
ETA: I should clarify here. I think the prevailing controlled thermite demo CT is that the plane did in fact strike the tower, but the collapse was initiated by thermite. This doesn't hold much water with me, since the impact of the crash would have obliterated the triggering mechanism for any thermite that was clandestinely placed there. The other way you can go with this is that the thermite was "painted on" certain structures beforehand, and the fire from the plane crash ignited the thermite and destroyed the core columns. Besides being patently ridiculous, the second scenario depends on a gross misunderstanding of the weight distribution and support properties of the WTC. It also would require the pilot to crash the plane at exactly the correct spot.
(The other, more sensible alternative, is that Steven Jones' "iron microspheres" are an expected result of the cataclysm - and not an indication that thermite was used.)
It's also not used for large-scale building demolition. That takes weeks of careful preparation with an empty structure that's already been gutted of everything.
As far as "nano-thermite" - there has been some laboratory experimentation into something called sol-gel nanothermite, but I don't think it's ever been fielded past the proof-of-concept phase.
I'm certain there are other posters here that have better information though.

In Dr. Jones's paper (http://www.bentham-open.org/pages/content.php?TOCPJ/2009/00000002/00000001/7TOCPJ.SGM)at Bentham, he references work by a few scientists -- principal among them, Dr. Tillotson at LLNL -- who are legitimately researching nanothermite. So the answer is Yes, it does exist. The first papers on it came out in 2001, I believe.
However, it exists in extremely small quantities, and as far as I can tell has never been applied outside the laboratory.
It certainly has not been demonstrated cutting structural steel. Its properties are also such that it doesn't seem even remotely suitable for the task. As an explosive, it is difficult to ignite and low-powered. As an incendiary, it is of low heat content even compared to ordinary thermite, which also has not been demonstrated in such a context. Cast into a "sol-gel," it is also of low density -- the "gel" is related to aerogel, which is only a bit denser than smoke. It appears to be expensive (at best) to manufacture in large quantities. Dr. Jones and his co-authors speculate that tens or hundreds of tons would be required, and presumably applied in layers a few microns thick...
Dr. Jones's paper, referring to the existence of laboratory nanothermite and speculating that it's ready to topple skyscrapers, is rather like inferring from the existence of laser pointers that orbiting deathsats could have destroyed the buildings with beam weapons. It's perhaps physically possible, but so impractical as to beggar belief.
ETA: Here (https://www.llnl.gov/str/RSimpson.html) is a layman's treatment from LLNL. The key feature is high temperature, which is achieved because the heat content is high relative to the mass and thermal capacity of the reactants. However, the total heat content is absurdly small, about 1/20th that of ordinary paper, pound for pound. Thus, the best use of nanothermite is where tiny, precise application of extreme heat is valuable -- melting tiny platinum wires, applying to miniscule samples of moon rock to boil off volatiles for spectroscopy, that kind of thing. Burning through huge steel columns? Heck, no.

Nano-thermite is whatever the person arguing that jews blew up the WTC needs it to be. If he needs it to create loud explosive noises it does that. If he needs it to be immune to plane impacts it does that. If he needs it to persists weeks after detonation it'll do that.
It's basically Schrodingers Cat for paranoid inbreds.

What's even more compelling to me (as Ryan pointed out) then its existence or lack thereof, is the fact Thermite would be one of the least reliable OR reasonable manner to "cut" steel nonetheless destroy a building. Reasonable to melt holes into steel? Yes. Cut steel? Not at all. And from what i've heard nano-thermite was in the infant stages of development (i.e. only existed on paper) in 2001.

There's a lengthy thread discussing Harrit et al in considerable detail at
http://forums.randi.org/showthread.php?t=140017 which should fill you in on both sides of the discussion. Be warned, though, this gets extremely technically involved.
The clincher for me that this doesn't indicate thermite is that the energy content is too high. Materials that burn in air tend to have much higher energy densities than those, such as thermite, that contain their own source of oxygen; typically, combustible hydrocarbons tend to have around ten times the energy density of thermite. Harrit et al's samples show energy densities higher than thermite even without accounting for the fact that part of the sample is an inert material. This in itself is clear evidence that combustion is taking place in their experiments, which in turn means that there cannot be certainty that any other exothermic reaction is taking place.
However, there are other, equally significant, flaws in their analysis identified in the thread.

I would like to know what the critical mass of this nanothemite is . The DDT
(Defraglation to Detonation Transistion) point. How much nanothermite is needed to make that happen .
This is the point where the reaction is no longer carried on by heat , where the pressure wave becomes strong enough to keep the reaction going .
This is important to be able to determine if it can be any use as blasting material .
I doubt that , also because it releases solids and not gases like high explosive compounts do.
I do not believe it can be used to slowly melt trough those massive steel columns.

I don't know about the DDT, but I believe you're correct about not being able to melt steel columns.
However, nanothermite is not being postulated for melting AFAIK. For this, Regular Thermite/Thermate is the supposed culprit.Problem is, this too is sheer speculation, since it has never been demonstrated to have this ability - that is, melting laterally thru a vertical column!

'Thermite' or 'nanothermite' requires a consistant high temperature (such as a blow torch) to ignite. It is notoriously unpredictable, difficult to ignite and control. Thin layers painted on would not be sufficient. Bags and bags of the stuf would have to packed around each column and at specific sites on evry floor.
It burns similar to a sparkler that kids get on bonfire (Guy Forkes) night. Conventional ignition methods of electric dets of knotted det cord (fuse instantanious) just wouldnt work as an initiation. No 'pressure wave' would exist as 'thermite' does not explode -it burns profusely and creates large amounts of smoke and light (imagine a roman candle).
The twoofers would have you believe that it was detonated and exploded and that this stuff burned its way through the columns or down the length of the columns without smoke or extreme bright light. Pathetic and ridiculous.

I much preferred the theory I once saw that C4 was actually inserted in the concrete slabs when they were originally built in anticipation of the future plans to blow the place up. Sounds so much more devious than "nanothermite".

Actually, you can't think of nanothermite like that -- it doesn't fit most typical models of explosives. One of those reasons, as you correctly note, is that it doesn't give off a great deal of gas when it reacts, and thus there is little volumetric change. This means not only does it not exert a high pressure on other objects, but it also creates a rather weak pressure wave, one insufficiently high to trigger a sustaining reaction.
Before I get into that, however, it should be noted that the precise mixtures created by Dr. Tillotson et al. are not "pure" thermite, i.e. not simply aluminum and iron oxide or replacement metals. Their "sol-gel" construction involves a matrix of organics, in some cases using a synthetic rubber compound called Viton. With sufficient heat, this additional substance can flash to gas phase, and is no longer just ballast. However, if you do want to drive a pressure pulse with nanothermite, this creates another tradeoff -- the Viton, or whatever else you want to use to creat a driving gas, will cut into your energy density even further.
Pure, ordinary thermite only contains about 4 MJ/kg of chemical energy. Nanothermite, because as the aluminum gets milled finer the inert aluminum oxide shell on the particles becomes a significant fraction of its total mass, is even lower density; Dr. Tillotson remarks about 1.5 MJ/kg is typical. If you then replace some of these ingredients with (potentially flammable, but requiring oxygen) Viton, you're going to reduce that energy density even further. And again, just for comparison, gasoline is about 40 MJ/kg.
Back to the original question, nanothermite can actually react with a supersonic flame front. However, as far as I can determine, this is caused strictly by thermal effects, such as radiation, and not through compression. There is no applicable Rankine-Hugoniot curve since compressing the nanothermite itself could lead to a temperature rise, but through different mechanisms, such as abrasion between the tiny little particles.
The upshot is that nanothermite can be a high explosive, but this is solely a function of grain size which drives the speed of the flame front. Because it is not a pressure-driven effect, while it can still produce a shockwave, it will be a particularly weak one. Unless packed with some medium that produces a large volumetric change when heated, it is unlikely to create much of an explosion. If so packed, it will be in all likelihood the least energetic explosive known to science.
I think the melting angle is less ludicrous than treating it like an explosive, personally. Thermite does, nonetheless, retain the ability to create high temperatures. But if used in this fashion I just don't see what making it "nano" would buy you.
Nor have I ever seen a plausible explanation for how it was controlled after it reacted. Again, see the Mythbusters exercise (http://www.youtube.com/watch?v=PPAYZMzGMwQ), using 1000 pounds of thermite, which didn't even come close to totally melting a light truck chassis. This demonstrates just how meager its effect can be on steel until the issue of controlling it is solved. It just isn't an efficient approach.

Agreed to all of that. While it can be laudable that a researcher attempts to answer all issues - and the "sounds" of explosions is one of those issues when we're talking the Twin Towers - in this specific case it's less an attempt to neatly fit observations and more an attempt to force a thesis into a mold that'll be accepted by everyone.
Ryan's right: Proposing thermite as something that melted steel columns would be far less insane than proposing it as an explosive. For starters, why not use real explosives? For two, as has been pointed out by damn near every sane observer, the explosive "noises" have alternate, logical explanations, so it would be entirely internally consistent to say "thermite melts, the sounds were due to something else". But to try to make thermite responsible for both the "melting" and the "explosions"... well, that makes our job easier, since it provides multiple ways to disprove the proposal (no evidence of column melting (no, for the bazillionth time, the eutectic erosion is not such evidence), no evidence of spalling or other effects of blowing up metal). But it does no good for the person advocating the theory because now the evidence has to be consistent in two directions simultaneously. And when it's not, the thesis is sunk. Again, no real signs of column melting, no "shrapnel" shredding people, parked cars, and buildings, the thesis fails. But apologists continue to cite it as gospel, just because it looks "sciency".
Resorting to a proposal of nanothermite as an explosive is most definitely taking the more insane track. It doesn't save you weight or volume, it sure as heck doesn't allow the evidence of the supposed destruction to escape notice, and it most certainly doesn't gain you any advantages over either regular thermite (to just melt the columns apart) or conventional explosives. But, it allows researchers to take materials expected to be found in the WTC rubble (iron oxide and aluminum) and make a conspiracy out of it anyway, which is definitely a neat trick. Throw in some layers of seemingly respectible observations, misdirect with unsupportable conclusions, and suddenly you have "proof" of what's not actually there. And it suddenly takes people with uncommon knowledge (like Sunstealer, who says he's a materials scientist) to work through the proof. More ludicrous, yes. But also more deliberate, which is why I'm willing to put the label of "liar" on Jones and his cohorts rather than "mistaken". They have to know at some level that their thesis is full of it; too many contradictions with known facts, and too many contortions required to make the thesis fit. But, they run with it anyway. The lure of applause from the non-critical thinkers must be too appealing.
Ryan's right when he condemns nanothermite "explosives" as the more ludicrous of the possibilities. But the fact such proposals are ludicrous doesn't matter to those who's agenda is to force a point into public perception by miscasting evidence. The more important thing to the conspiracy peddlers is to shape the narrative, and such ludicrous proposals allow them to do so. Doesn't matter that truth suffers in the end.

When he makes these huge claims , he'd better have a decent and complete theory to back it up .
Ive worked with thermite ,and know that it is very far from being a high explosive. Especially the Fe thermite isnt very powerfull , CuO3 as an oxidizer is more powerfull but still completely diffrent from H.E.'s
Even if thermite releases more total energy than certain high explosives , it's reaction is still much to slow, and therefore useless for blasting columns.

Eventually this thermite theory is going to implode under the weight of it's implausibility. Nobody, including Jones, has offered anything but the most weak and vague hypothesis as to HOW WTC 1, 2 and 7 could have been brought down by thermite, let alone even begin to identify some real perpetrators to pursue.
Kevin Ryan is casting suspicion at various companies, some of which contributed to the NIST report;http://911review.com/articles/ryan/nist_thermite_connection.html Jones alludes to military programs.
Perhaps the most ludicrous element is that they claim a vast government conspiracy on one hand, then want the government (by way of some kind of 'investigation') to reveal and prosecute the conspirators. They do not seem to care that, if their claims were true, then the government would certainly not be in a position to police itself anyway....

As I have posted elsewhere, if anyone presents you with the Jones bullcrap, simply show them this. In response to calculations that Dr. Frank Greening presented to Jones et al, their response, was the following,
So when I bounced my calculations and conclusions off Jones et al, all he could come up with was the suggestion that there were probably other explosives used in the WTC and the nanothermite chips were maybe just fuses!
http://the911forum.freeforums.org/active-thermitic-material-in-wtc-dust-t150-30.html
So when pushed by Greening with evidence that would make the suggestion of his nanothermite chips used to melt the steel columns seem ridiculous, Jones suggests that his thermite, all this hooplah, is over "fuses" for traditional explosives.
Seriously...you can't make this crap up!
