I have looked and looked, but I have never found a VOD for NI3. Does anyone know what the VOD is? Is NI3 a good intitiator?

The Author of the PMJB series(Kurt Saxon, wonderful man I talked to him over the phone once) Claims to be able to use it initiate Pipe Bombs, and says the a piece(the size of a bean) aplied wet to the end of a 1/4Stick will set it off. He aslo claims to use it to rid himself of rats.

Bad idea. You should look at megalomania's site about Nitrogen Triiodide. In a controlled laboratory experiment, a pile of this composition was initiated with a feather.

but megas site does not give the VoD. I doubt you are going to find one that is accurate. The NI3 is SO sensitive to everything, i doubt you can really test it.

Yeah, I kind of thought that could be the case, but I thought maybe someone tested it. Oh well......

NI3 is unbeleveibly sensitive it will go of in slight heat changes! if you blow on it it will go off, that means even your air conditioning could set it off! also when it goes off it stains everything purple

I think that nobody really wants to play with such a compound, dry and to put it a tmax density in a pipe (min 500g) to determine the VOD of that shit!
It is fun to play with one gram of it but insane to manipulate it dry!
A 0.5g pellet will detonate by the contact of a fly landing on it!I have played a lot with that compound in my early times!

Why is this in "Low Explosives"? I'd class NH3•NI3 as a HE. It certainly does not deflagrate (no oxygen)! And from demonstrations I've seen, this stuff certainly is a lot more powerful than flash powder.

How do you actually calculate the VoD of explosives?

With two methods:
*an ultrafast chronometer set on and off by the shock wave passing trough two sensors; the on and the off sensors being separated by a known distance!
Ex: 5 meters and 0.100 ms that makes 5m/0.100ms*1000ms/s = 5000m/s!
*The other way is more complicated to explain but roughly it is a comparison of VOD's with a detcord having a known VOD!
The detcord makes a loop that has a detonator in both extremities of a 1 meter pipe containing the unknown explosive!
At a certain point the detcord and the pipe detonates separately at their speed and then when the end of the 1m pipe is reached it set off the second extremity of the detcord which is already detonating at the other extremity for a while! So you have two shockwave traveling towards each other and they meet at a certain point that is indicated by a dent in a load plate rolled arround the half of the detcord near the last extremity! The relation is easy to find out by an algebrical equation!And thus the place of the dent is proportionnal to the speed of the unknown explosive's VOD but also of the detcord's VOD what is known!

I feel the need to say that NI3 has absolutely no practical use whatsoever. Using it as a detonator would be suicide. It should really only be regarded as a fun novelty, as that is all NI3 is. It is powerful enough to cause a lot of damage to a person, even death. Remember that NI3 is still an explosive, even though it is fun to play with.

Is ammonium triiodide any safer? I've read a lot about it on kewl sites.


And Philou should really cut down on his exclamation point use. It mars otherwise impeccable english.

[And you shouldn't be telling respected members how to write, ALENG]

Ammonium tri-iodide is just another name for nitrogen tri-iodide. Both are NI3, the very same thing.

Ammonium triiodide just not exists in normal conditions because ammonium cation is (+1) valenced and iodide anion is (-1).Therefore ammonium iodide is NH4I and i won't say it is same as NI3.NH3

When NI3 is dry it doesn't even need a feather to set it off it can go off by itself without any outside disturbance. Sensitivity of NI3 is directly related to its moisture content and I would imagine so would its VOD. I've read somewhere that when that stuff is very dry its VOD is aroud 5000m/s.
I don't know about this stuff being powerful enough to kill, as someone said before b/c you are not very likely to be able to successfully dry a chunk that's big enough to do that (assuming you are not going to stuff your ear with it), but I never tried big chunks myself.
One word of warning though, don't try to store this stuff in ammonia either, it tends to form blocks that dry up from the inside... not good!

I am curious, WHY does anyone want to make this explosive? It makes no sense to me that anyone would want to make something that are so sensitive that it can be set off by wind blowing at it.
maybee (not for me though) as a "one timer" just to have done it, but to PLAY with it??

I made it when I blagged some I crystals from my school years ago. I made it just of of curiosity, for an experiment.

the only possible use for NI3 i can think of is using it as a cruel form of practical joke
asting some whet stuff on a pavement, and when it dries it gives quite a shock to pedestrians.
i seen to remember someone on here telling me about how some Uni professors used to do this for their kicks

It's very nice to play with. Very simple to make. Very fast. That's why everybody wants to make it.

As about vod, should be rather small when when, as is not able to tear the filter paper, I'd say under 1000 m/sec

It definitly can kill you. Imagine 1 gram of NI3 exploding in a beaker. Sharp pieces of glass flying at supersonic speeds. At least one (small) piece passing thru the eye and entering into the brain. Any explosive can kill you. It's a matter of quantity, but you can get killed with less than a gram if you are unlucky enough.

I made it before, until the beaker which contained the stuff exploded with no apparent reason. The NI3 was stored under water, and it was less than a gram. The beaker was turned into dust; it was a 250 ml one; the largest pieces of glass I could find were deeply embeded into a plank of wood.

Just for the record, a triiodide anion does exist, it has 3 atoms of iodine and a single negative charge, its also the reason iodine dissolves well in potassium iodide solutions. Ammonium triiodide should be preperable, though we wouldnt expect it to be explosive.

Yes it does but i don't think that pure (or solid) NH4I3 will be available.
It should be like this (conjecture only):
KI + H2O --> K+ + I-
I- + I2 --> I3-
NH4+ + I3- --> NH4I3 but we cannot say that it will.

Edited twice: First i searched for sup and sub tags and found that thread :) , edited my post to add su{b|p}s, and seemed it doesn't works :mad: and removed them

In http://www.roguesci.org/theforum/showthread.php?s=&threadid=1474&highlight=subscript+superscript sub and sup's work or is it an old (a very old) thread? or i miss sthg?

Infinie, use the '< > < />' tags for ^sup and _sub .
The new board software doesn't allow the ()(/) tags for subscript or superscript(is that it?).
