I have semi related question. Since both RP and iodine are used to make methamphetamine, why is iodine easer to get? Sure it's still kind of illegal, but you can still buy it. It's on United Nuclear (you can only get an ounce though.) I wish it was the other way around, since iodine is easer to make too. Not that I would ever even consider making methamphetamine.

Mainly because its other uses are far more economically useful and less replaceable than RP - although that hasn't stopped the DEA from trying to phase out iodine.

Ok, thanks. That makes sense... Another reason that I just though of is because they know that iodine is easy to make, so if cooks could buy RP, and make iodine...

Red phosphorous and arsenic sulfide (As4S4, realgar) are hard to come by these days. Considering how many people lost bits and pieces to pyro using these with Potassium chlorate, it might not be such a terrible thing.

I did see a supplier of oil paint pigment materials selling realgar a short while back. For an insane price-

Ah yes. He's got cinnabar (HgS) too?

Haha, who wants to buy this and distribute it? Minimum order is 19 metric tons :P It would be hilarious if it managed to get by customs, and you actually ended up with it! The DEA would freak out if they ever found out.

Anybody know why RPis always used instead of white phosphorous? Aside from the volatility of WP, why isn't it just used instead of RP?

RP doesn't need special handling as WP does.
RP can be acquired from the striking surface of match books/boxes.

It isn't always used instead, some people use white phosphorous as well. But the main reasons are, it spontaneously ignites in air, and it's quite toxic as well, also the heat from skin can cause premature ignition. It's cool for science demonstrations (eg. burning in pure oxygen), but dangerous and hard to get.
Is it true that white phosphorous turns into a different allotrope over time?

Does Nitrogen gas expand more at high temperature or Carbon monoxide? I know they're very similar in molar masses but does one gas expand more or less? Expansion of gases sometimes are not perfect, for example CO2 can obtain different volumes with same pressure.

Plasticizing MHN?


I was wondering if anybody knows if MHN can be safely plasticized in the same manner as PETN or ETN using polybutene? i dont see why not, except the sensitivity being greater than ETN-PETN may be a cause for worry. if i choose to do so i want to do it as safely as possible and being sure that it wont go off in my face. any answers would be greatly appreciated.

plasticizers


Can i dissolve any polubutylene/polyisobutylene material with any solvent, add then the EM and the motor oil, and let then the solvent to evaporate ? will it work or it just need a resin-hardener mix ?

Quote: Originally posted by underground  
Cause i do not want to open a new topic for only a short question, that i want to ask is:

The amount of primary-booster that is going to detonate an amount of secondary explosive like ANNMAL or ANFO always is going to be the same ? or it must be increased as the secondary explosive increases ?

For example, 3gr of ETN and 500mg of HMTD can easily detonate an amount of 300gr of ANNMAL - ANFO. Now if the ammount of ANNMAL - ANFO changed to 300kgr, the 3gr of ETN and 500mg of HMTD would be enough ?


Does anyone have the answer ?

I was wondering if anyone has ever tried ETN/NC composite ?
Say 70% ETN + 30% NC with Acetone as solvent
Or even replace say 5% NC with synthetic oil to make flexible.

can TNP be made from salicylic Acid sulfuric acid and ammonium nitrate i have not seen any reports of it being done with ammonium but just checking so im not wasting my time i dont see why it wouldnt work though?

It works, but Sodium nitrate has a reputation for working better-

See: " Rosco's Good Old Country Recipe for Picric Acid "

A few moments searching on the site would have shown you that-

AN NM SA is a good explosive. My question, ANNMSA+AL, would that be a better one? As in more sensitive? I realize the aluminum would dissolve creating hydrogen, but it would still be there, right?

I can make either Acetone Peroxide or Picric Acid, which is more stable? I think Picric is more stable, but if there is not a big difference, I would prefer to make AP.

There is a BIG difference in stablilty and performance aswell.
There is numerous threads about the stability of AP.
Picric acid would be a much better choice.

Does hydroxylammonium salt of azide, dinitrourea, dinitroguanidine exist? I havent found much information on them.

Fedoroff doesn't mention any other salts than the nitrate, perchlorate, sulfate, acid sulfate and hydrochloride. It is however claimed that hydroxylamine will form salts with most strong acids. My guess is that other salts can be prepared from hydroxylammonium sulfate solution and a barium salt. Hydroxylammonium sulfate seems pretty simple to prepare too.

The universe is hypothesized to start from big bang, a singularity. Which means the density is infinite. So according to all equations to calculate Detonation velocity I know of, the VoD of big bang will be infinite m/s since the density is infinite?

Yes, this is how it is commercially produced as well, best way is to dissolve PB/PIB in solvent, add plasticizer/motoroil, then add EM and stirr gently. You can also add the EM to water and stirr while adding the binder/plasticizer/solvent mix, this will give an even coating of the EM crystals.

In general , you don't need to increase the detonator strength with increasing amounts of secondary.

The laws of physics as currently known do not apply to those conditions.

Very good!!! So with any source of PIB (like rubber PIB gloves) a SAE 10 motor oil and a solvent, a really good plasticizer can be made for any EM!! Have you got any info about that or any DIY guide ?

Very interesting, so that means that a 100kgr, and over of ANFO, can fully be detonated with only 4-5gr of ETN ?? !!
