List of Binary Explosives?

Hey guys, Any idea where I could find a good list of the known binary formulas?

Look into Sprengel explosives and panclastites. Interesting and some very sensitive.

My Sprengel test:

do you mean explosives with many ingredients? then all plastic bonded explosives, such as C4, are in the list.

TNM and liquid fuel
HNE and oxygen negative explosives like TNT and tetryl
HNO3 and liquid fuel like NM or partially nitrated hydrocarbons
AN and NM, fuel oil, Al or TNT
Na or KClO3 with fuels like partially nitrated hydrocarbons
Na or KClO4 with fuels like partially nitrated hydrocarbons
LOX and fuel

explosives as in primary or secondary?

although some might function as partially primary but probably not HE primaries here are some with AN, NH4NO3

AN / C aka ammonpulver
85 15

AN / Su (sucrose, sugar) aka sugar dynamon (dyn-amite amon-ium nitrate?)
72.7 - 95, 72.7 being near if not perfect OB but quite hard to set off, 1.5g PETN wouldnt set off 20g ANSU properly

AN / Al (ammonal, ANAl)
82 - 95% of AN used, 5% Al is the best if you want sensitivity / lowest critical diameter

AN / Mg (i suppose this is seldom to see people use, because magnesium is quite reactive and you dont want that with a hygroscopic material)
95 5?

AN / FO (diesel)
95 5 (this works best with prills of AN and is quite insensitive and often requires large diameter charges)

not to mention NH4ClO4 / Al

AMP / Al
80 20 although AMP by itself is an explosive with great properties, very brisant but also expensive if you can even find a store selling it

KClO3 / Vaseline aka Cheddite C
91 9

KClO3 / Sugar aka 'white powder'
71.5 28.5 you should take care that fuse doesnt go near charge as its a flare composition and burns not only hot but also without much heat

Thanks, What is AMP?

Dornier 335A - 18-1-2014 at 01:18

I'm quite sure he means ammonium perchlorate.

I do not see how Ammonium Nitrate compositions classify as binary.
NH4NO3 is an explosive in itself. All the additives simply enhance the performance and may sensitize it depending on the additive.

Have you ever tried to detonate pure ammonium nitrate? It is so insensitive that it could hardly be considered an explosive, save for large amount and during extreme conditions, like in an indusrial or large fire, or large scale accident. Maybe molten AN, but even then, often trace metal imurities act to sensitize it.

The addition of at least a few percents of one or more sensitizers and/or fuel is needed for any practical use at all.

I think what he is asking about is two different compounds, that when mixed form a sensitized explosive, but each compound alone is not detonable. I think some early armaments in the world wars used these types of mixes in aerial dropped shells. They mixed when dropped, and after the compounds were mixed, they were so sensitive that the impact of the shell was enough for detonation. No fuze needed.


Panclastites are a class of Sprengel explosives...

"During World War I, due to shortages of other explosives, French used some panclastite-class mixtures, which they called anilites, in small aircraft bombs. The mixing of the chemicals was triggered by airflow spinning a propeller on the nose of the bomb after it was dropped, mixing the previously separated chemicals inside. The resulting mixture was so sensitive the bombs did not need a fuze to explode on impact.

In the 1880s, Germans were testing torpedoes with panclastite warhead. Carbon disulfide and nitrogen tetroxide were stored in separate glass compartments, which were broken when the torpedo was launched and the chemicals mixed, and later were detonated by a contact fuse." ~ Wikipedia

Fantasma4500 - 19-1-2014 at 06:11

yes i meant NH4ClO4, ammonium perchlorate

however, CCl4 + Al
and cheddites
not to mention armstrongs mix and flashpowders

anyhow be more specific, theres many different things, such as flashpowder which wont (usually) be considered high explosive and by that possibly not be considered an explosive but rather a pyrotechnical composition

PLX (NM/DETA) 95:5 is also good explosive

About AN mixtures, try AN/Al/Xylene 90:8:2. VoD 4200m/s. Stronger than classic ammonal
Options for fuel AN mixtures are endless. Dynamons are mixtures of ammonium nitrate with solid fuels. Detonation velocity 1500 - 4200 m / s Require well been dried ammonium nitrate, a maximum fine grind components and excellent homogenization. They tend to resealable and subsidence, resulting in partial loss of detonation capability. The presence of 3-5% of aluminum results in an increase in efficiency and sensitivity to initiation. There are countless variations on the theme dynamons. Reportedly the most - a powerful combination of 90% ammonium nitrate and 10% powder of fir or pine cones - Detonation velocity 4200 m/s
Here I test with sugar and milk powder :D
