What would the purpose of a thermite "booster" be? I would think a faster reaction and more energy released. According to wikipedia, military thermite mixtures, such as the kind you might find in thermite grenades or bombs, have a few other ingredients.
The one that stands out most is barium nitrate, which acts as a booster and lowers the ignition temp, which is critical for practical thermite use.
A chlorate booster sounds impractical at best, if not dangerous. As ramses implied, KClO3 and aluminum make a flash powder that is sensitive to friction, shock, and a number of impurities including sulfur and acids. While I don't doubt it could hasten the thermite reaction in some way, there seem to be better ways to do this that are already established.
I would much rather see perchlorate used as a booster, but god knows what would happen there as perchlorate+AL makes a much more powerful flash powder, albeit less sensitive.

I think uber sensitive covers all of those sensitivities. and i don't think perchlorate isn't more powerful, it just has 1 more Oxygen for the same NaCl. even if it is more powerful, not by much.

Let me tell you, industries use tons of thermite for production daily and big charges.

Thermate mainly had sulfur in addition to thermite and thus cuts iron very fast via formation of the eutectic and used in thermate cutter charges. But that is not what we want.

The military applications probably need the Ba(NO3)2 but this is not what we want. At best it is used for ignition. I am still not clear why the cation Ba is special. Its v poisonous and difficult to procure. I would want to use a benign nitrate. Its only at the starting tip.

Again, Let me tell you, industries use tons of thermite for production daily and big charges and the boosters. This means our knowledge is incomplete and we are just guessing. I have already said, those who have library accesses should try to get and share the docs and we can all study together. I would do it if my public library had any of this. They dont even have JACS. All they have are adult or children's books.
They dont deem the public to be deserving to read JACS.
On the other hand, the moscow public library has miles of shelves of books.
The criminals in the govt and their cronies in the industry are stealing our tax payer money like that MEGA SCAM ENRON which is only TIP OF THE ICEBERG and giving it to HALLIBURTON AND DEFENSE industries. Massive inflation is eating away everything.
And what is this "uber sesnsitive" ?
Does anyone have a writeup of the "current state of knowledge on thermite, empirical and theoretical" based on the work in this forum and its predicessor forum to share ? I am sure those who are doing it have done a study like this and can they generously share ? Successful Recipes, failed Recipes ... photos, videos but also of the grunt work and all steps, not just a show of the final result.
Lets brain-storm together and collect all the definitive knowledge into a single writeup.

There's really quite alot of stuff on the web about thermite and boosted versions of it. As usual with the web, quite a lot of it is dross. Censorship certainly hasn't kept this stuff out of the public domain.
Here is the website for JACS As you can see, it covers some really obscure stuff; most people in the local library couldn't read the titles nevermind understand them. It would be a waste of the library's (and thereby the taxpayer's) money to subscribe to it. In any event, you won't see much there about thermite because the people who contribut to JACS grew out of that sort of thing ages ago.
If what you want to do is compile a list of experimental results from the inclusion of, for example, potassium chlorate, in thermite then go ahead. I will include the caveat that, if the stuff explodes, you might be in breach of the site rules. If you don't like those rules then I think your best bet is to set up your own website (good luck setting up one as successful as this). Ranting about politics has little to do with the basis of this site and nothing to do with chemistry. Accordingly, I'm sure we would prefer that you didn't do so. If you have any questions about actual chemistry feel free to ask them.

Zilch empirical or theoretical scientific info. JACS link trivial. third para full of ambiguities, threats of failure, devoid of any scientific info., indeed a high level spooky skill, but of no use in science. These spooks intend to create a knowledge apartheid, as if chemistry is of no use to common people.
you spent a lot of time crafting this ambiguous paranoia producing para. must have a lot of smoldering acid in you for this motivation.
If talking about rights of access to info is politics, then science begins with it.

I have no idea either, but it looks like it has taken a political turn again. I don't see how this thread can result in anything positive for anyone, so I'll close it.
