Mixing HMTD with urea nitrate or ammonium nitrate


Guys i know this topic might be looking unappropiate . Guys i know mixing HMTD with urea nitrate or ammonium nitrate is a deadly wish and i am not going to mix them. I want to know that how does people mix HMTD with urea nitrate or ammonium nitrate . Do they use any solvent for mixing them or they use to mix it in water and then let it to evaporate or they mix the dry powdered urea nitrate with HMTD .

The preferred embodiment is to introduce HMTD inside of an aluminum tube
lined with polyethylene film and topped with a pyrotechnic priming charge.
This then can be placed into a booster charge to set off the urea nitrate.

I am not talking how to set urea nitrate i am asking that how can we mix ammonium or urea nitrate with HMTD

Blend the AN with 2% lampblack or charcoal beforehand. Put in a paper cup. Just toss the HMTD on top of the AN... Attach cup to a long stick and shake. Works fine...

The charcoal tells you if it's fully mixed or not. If it's not fully mixed it is more hazardous. Good stuff... 5000+m/s and a good 1+ RE IMO. Use like 83/17 AN/HMTD oxygen balanced... Needs a lot of flash(5g+ Confined Flash) or a cap. It's only like 1/3rd less shock sensitive than HMTD even when the AN is blended extremely fine to prevent friction.

HMTD has very low reactivity to aluminum. Weeks in contact at room temperature and no change in aluminum or HMTD. Inspected clean shiny aluminum with microscope.

Thanks the messenger I think 50 : 50 ammonium nitrate with HMTD is flame sensitive and doesnt need a blasting cap and it can be detonated by flame.

I should've figured that guys who make such dump mixtures wouldn't care anyway about how fine are the particles and how well are mixed.

I think the finer the particles the more effective it will works . When you are making 50:50 mixtures extreme care should be taken because it can explode

No need for extreme care. You are either prepared to die or not. I would mix them only if it's like that I'm in prison and it's the only way to break open my cell. And from MEKP, AP, HMTD-HMTD is the most sensitive and worst fuel and generally comes in bigger crystals.

nice joke ral123 but HMTD is generally powder.

Needles, crystals, I dont know what, it takes more time then ap and I'm pretty sure it'll be with bigger particle size then my fast low tempreture synth of ap.

ral123 i have made HMTD lots of time and i always get extremely fine powder. by the way in jail you wont be having access to all these chemicals to make bombs there

@Vikascoder I wouldn't say that, if your in a medium or low secure prison you can actually make explosives.

Anyway, dry HMTD, contacted by flame, spits up a flame 10' high. Just shy of explodes. So I don't see why admixture w/ something much less sensitive would make a positive difference here. The only time I have gotten HMTD to go off on it's own, was to slowly heat/dehydrate it. Once you exclude every last molecule of water in there, it can go off high velocity through simple application of additional heat. Scarey shit. I'd never mess around w/ explosives ever again.

HMTD normally deflagrates by simple ignition!
Heating on a plate will cause it to detonate ─ on slow heating, though, it may simply decompose . . .

i heated my HMTD on my heating plate then it just deflagrated with a puff sound . My HMTD only detonates with shock . Is there any possible way to detonate it in open without providing shock.

i had 7g of that Mixture (~75/25 - AN/HMTD)...put it into a hole in the ground with normal fuse and that worked pretty well...shit was loud as hell and dirt flyin everywhere :o

Gentlemen:
I don't see any chemistry or physics discussed here. An Energetic Peroxide mixed with many nitrates will yield a reaction from flame. Yet what is taking place is a "thinning" of the energetic material. In order to learn understand water-gel component, the peroxide is inappropriate. Water-gels (an INDUSTRIAL water-gel) are generally a slow "shoving" design, that are sealed and initiated by explosive train dynamics. There are complexities therein as (water-gels) are often made from de-milled energetics and the volume of water is formulated to increase density.
The warning re: peroxides is appropriate. They do not belong DRY industrial / potential shock agenda. Mixing an energetic peroxide with a dry nitrate is a prescription for a problem (friction) and adds nothing to the energy yield.

IF there IS a source material of mix nitrate, etc - it should always be quoted here, so that the concept may be examined in full light of detail and application.

Once I made similar mixture- TATP + AN. I told many times, that TATP is not something extremely dangerous (compared with another primaries, of course), but here I have to agree with majority. It was not the most clever experiment and I'll never do it again.

@Caterpillar what was the ratio of T.A.T.P and AN and what results did you found after mixing them

I do not remember now, it was in 1977. Something like 50:50. Does it matter? It exploded after ignition. It was the longest day in a year- June 20. Just after mixing I had no result (or, more precisely- result was that it didn't exploded during mixing). 20-30 gr, something like this.

Normally a ratio of 90AN/10 AP remains sensitive enough to detonate with a AP blasting cap yet insensitive enough to be handled with reasonable safety. Note that I said reasonable safety, meaning handle with care and use your common sense. I'm not going to ramble on about safety, if you are willing enough to use sensitive energetics then you should be willing to read up on safety before you do anything.

Back to the point, I could never set that ratio off by just using flame or heat. It had to be set off using a small but powerful blasting cap.

How did you mix them and at what density? The ap/hmtd must be there as a fuel also, not only as sensitive component, may be if they wouldn't be well mixed it's better to add a little fuel also.
