You try anything, any aluminium, any tube. But is time something really try. Also, I don't know everything. Brass tube is expensive? Or copper tube is more thick and expensive also? And what your hands and classic primary. Hands is not expensive?

@Laboratory of Liptakov,
What does CHP stands for in your videos?
I hope not Copper hydrazine Perchlorate (way too unstable) ... maybe Cobalt Hydrazine Perchlorate?

You had troubles with pure NiHN detonator because you need a serious kick...
I usually use Silver acetylide nitrato complex for 1/4 to 1/3 of the mix: both NiHN and AgANC are compatible and clayish material.

PHILOU Zrealone - 7-11-2015 at 12:39

Just for those who wants to follow Laboratory of Liptakov process,
The pressure is applied and measured by a very smart OTC way.

Just in case here is the conversion factor in pressure per cm²:
Multiply all values for the 6 mm internal diameter by 3,53677651

Where does it come from?
pi*R²= 1 cm² = S
--> R= sqrt (1/pi) = 0,56418958 cm
and D = 2*R = 1,12837916 cm

But LL uses 6 mm diameter detonator (R=0,3 cm) in its system of pressing so the surface of pressing is much smaller:
0.3*0.3*pi = 0,28274333 cm²

And 1/0,28274333 = 3,53677651 is the conversion factor for pressure per cm²!

Thank you!

You had a good/smart idea to test copper perchlorate with HMTA: Cu(ClO4)2.C6H12N4 has better OB than
Zn(ClO4)2. 2 C6H12N4
Mn(ClO4)2. 2 C6H12N4
Ni(ClO4)2. 2 C6H12N4

Very nice article!

Investigation of other perchlorates complexes could be interesting:
Co(ClO4)2. 2 C6H12N4
Ni(ClO4)3. 2 C6H12N4 ... Ni(III) better OB than the Ni(II) one

But also tetraperchloratoaluminium [Al(ClO4)4](−) and hexaperchloratoaluminium [Al(ClO4)6]3(−) in admixture with HMTA diperchlorate or triperchlorate...

Laboratory of Liptakov - 8-11-2015 at 07:34

Thank you.
Good design/reason- those compounds of cobalt, nickel III, and aluminum. This is a large number of undiscovered compounds. As you can see, not all of it is explored in the field of energetic materials. An example might be just the CHP. Since in the latter tests showed the following: When using the CHP in a detonator does not need this condition - large grain. This is a big advantage. Since recrystallisation (production CHP) formed crystals of 0.6 -1 mm. The crystals need only be dried.
Use of the binder to the formed agglomerates 2x2 mm is not needed. It is better for handling security. A shorter production process. Next, important notice: How write Philou, for hole - cavity 6mm is presented absolute pressing value in Kg. Not for Kg on cm2. It's important for attempt everybody. The same values is possible used for a lot energetic mixture. ETN / Al / NCxy, CHP, TACP and has mixtured. Cavity of 6mm (or 1/4 inch) is universal around the world. For detonators. Usualy...... :cool:

hybride detonator

Laboratory of Liptakov - 11-11-2015 at 08:20

Here I introduce a new kind of mini detonator. Its construction is not pure NPED system, but the used materials are well known and understood. Transition DDT for clean NHN is difficult. Transition DDT for clean ETN is also difficult. However, their mixture (according to the scheme) has excellent properties of DDT. It works even 4 mm. Even better, it works mixture in the cavity 6mm, of course. I hope everything is clear from the picture.
Dr. Liptakov

Bert - 11-11-2015 at 12:36

I saw reference in the Indian article on metal/hexamine perchlorates to explosive sensitivities "between a primary and a secondary". And references to testing methods for heating to explosion- (deflagration? Detonation?!)

Is there anywhere published impact and friction sensitivities?

friction

Laboratory of Liptakov - 11-11-2015 at 13:06

Well. Information about metal hexamine perchlorates are incomplete. I have not better info. According last tests (Cu complex only) is friction - failed, no detonate, no deflagrate. But impact is similary as head from matches.
It is very no precise results, I know... :cool:

NPED Detonator

MineMan - 20-1-2016 at 14:13

Hello All,

After much experimentation I have come up with a NPED detonator that is 100% reliable so far using ETN, the secret is micron sized magnesium powder.

I mix the following:
80% ETN
10% Potassium Perchlorate
3% Aluminum powder (400mesh)
7% Magnesium powder (1-3microns)

The truth is, I have never measured, but it has worked with this approximate mixture, even being different each time. When the magnesium powder is added, the ETN can be lit and will react like flash powder... not so with only aluminum.

There is a another small trick, it must be tightly wrapped in 2 sections of aluminum foil.

Put 70-100mg of this mixture in 1 square inch of aluminum foil, inset the fuse, and then wrap/with the fingers.

Then put 500mg-1000mg in 4 square inches of aluminum foil, insert the above into it, making sure the fuse does not contact this material (the idea is to have it hit the 100mg of ETN first. Wrap with electrical tape and there it is.

The magnesium really is the key. Also, I hate throwing this out there, but I am a blasting engineer by profession... but I still have some questions for the experts (Bert,Rosco, ect) who deal more with this stuff then tons of ANFO. This mixture still seems quite impact sensitive, I have done about 40 hammer tests on it... not really any worse than regular ETN... but I still don't like rolling it in my fingers to produce this detonator? thoughts?

I think the next step is to try it with PETN so it is less sensitive.

You know I am curious to hear everyones feed back and results!

nitro-genes - 20-1-2016 at 16:54

Interesting, regular potassium perc+aluminium or magnesium flash powders are somewhat sensitive to friction (although relatively low) and static electricity, so these would be factors to determine as well to estimate the relative danger in respect to primary explosives.

Wonder how well a nitrocellulose or PTFE matrix would do to both bind the mixture and help DDT, instead of the perchlorate. Although PTFE would probably be to dangerous regarding toxicity of decomposition products.

TheAlchemistPirate - 20-1-2016 at 19:02

I have recently had success detonating ETN via heat shock and reaction with aluminum. Trying to make my ETN detonate in aluminum foil tests was incredibly frustrating for a while, until an incident at 11 pm one night with a pop can and the kitchen sink... My ears were ringing for a few hours after that. Long story short, aluminum foil doesn't seem sufficient for tests, and thicker aluminum sheeting is much more reliable.

-Back on topic-
My method involved forming a tube with the aluminum wall of a pop can, filling it with 3 parts KNO3 2 parts magnesium powder, and placing it inside another tube with 4 grams of ETN around it. I figured the high temperatures generated by the magnesium/KNO3 (1500+ oC!) would be enough to melt the explosive charge and cause it to react with the aluminum, causing detonation. It was a success! Now I must miniaturize this system to the size of a conventional blasting cap, which I have already put together and plan to test tomorrow. I'm still unsure of how much power this cap will generate, other than being able to detonate other ETN.

hissingnoise - 21-1-2016 at 02:29

Small quantities of Al or Mg powder mixed with confined, loose ETN, MHN or PETN detonate on ignition.

Dr. Liptakov

Laboratory of Liptakov - 25-1-2016 at 04:30

Hmm.. Hissing, you read patent on end? You was try this type a construction ? Results? How much attempts? On end author writing: For test was used system NONEL. Thus, shock wave with speed 2000m/s. (6500 ft.) If you everybody have the NONEL cable tube, OK. Good information. But I say, that PETN with 5% Al will be not working from hot wire od some deflagration mixture. I am lot attempts was do it. Allways failed with PETN.
Dr. Liptakov
Edit: Mine Man is on good way. Perchlorate, AP, PP, Al, Mg. But produce NPED on PETN based is more difficult. My recommended is added 20% NHN to PETN. But is not pure NPED, of course.

Dr. Liptakov,

Do you have any updated sensitivity information/tests for both TACP and CHP? After watching several of your videos, and the way you prepare these mixtures they seem at least less sensitive than ETN..? Would you compare them to PETN, RDX, or am I completely missing something?

NHN looks really promising, but as you said it's preparation is toxic...

sensitivity ETN RDX PETN

Laboratory of Liptakov - 30-7-2016 at 01:58

Perhaps accurately I do not understand all questions. Precise testing I am not tried. On friction and impact. Mainly properties for safety filling, is behavior of material, during pressing and especially, when you remove out remove the pressing rod. This operation is critical. Because small amount materal is get between rod and wall of cavity. At this operation is mainly this thing. Filling (press) EM, must be in a big grain. Usually 2 x 2 mm. If you use only big grain without fine powder, nothing material is get between rod and wall. The rod is possible remove out very easy and safety, of course. For example: Pure Lead azide and pure NiHN do it a big problem. Big amount is always between (after pressing) rod and wall of cavity. Very fine EM is a like a liquid. However for example grain 2x2 mm from NiHN + 7% nitrocelulose ( or 2% dextrine) is possible pressed on high press. And remove the rod is easy. Without scrunch. Same conditions and behavior pays for others filled materials. For example ETN 75 + Al 15 + NC3 10. Conditions is always use only bigger grain.
After this explanation, is not necessary putting a question, how material is sensitive. At this recommended operation, is less sensitive all. Maybe 10x less. Who spend a 1000 hours with manipulation with ETN, CHP, PETN, know what say.
....LL.... :cool:

PHILOU Zrealone - 30-7-2016 at 11:10

OK for the safety concern, but the other big question is what is practically better...
1°) big grains pressed -implies-> big bubbles --> few big voids.
2°) tiny grains pressed -implies-> tiny bubbles --> many tiny voids.
3°) mixed grain -implies-> optimal packing...in theory from beton and cement technology they use different diameter particles to acheive best packing, density and resistance towards breaking/cohesion. --> fewer tiny bubbles --> few tiny voids.

Maybe big and tiny bubbles helps into the D2D process just like microballoons to generate hot spots when the detonation waves passes through compressing the air gap adiabatically...for certain explosives it may sensitize them towards shock (for example MN, EGDN, NG... maybe ETN because of the same familly...).

PHILOU Zrealone - 9-11-2016 at 06:37

Yes some are exotic but into the reach of hobby chemist or chemist with some acces to chems.

Some perchlorates are quite unsoluble but others are very hygroscopic...same applies for organic amines.
N2H5ClO4 for example is very hygroscopic much more than N2H5NO3.

So the concept of
Amine.HCl + NaClO4 --> Amine.HClO4 + HCl
might aswel be counterside/counterproductive...
Amine.HCl + NaClO4 <==--> Amine.HClO4 + HCl

I would go for Amine.H2CO3 (carbonate), Amine.H2O (hydroxyde) or Amine (free base) + HClO4 directly.
In those last two:
-the products must be freezing cold and the neutralization (that produces a lot of heat) must be carried out very slowly
-or for the second (into water/as hydrate or hydroxyde) quite diluted --> then water must be driven out by evaporation/mild heating/dessicator.

PHILOU Zrealone - 9-11-2016 at 06:40

Ah yes also:

With successful was tested a new composition in system NPED. Condition is perfect pure ETN against reaction with permanganate. Aluminium was bright, color type silver. Permanganate is necessary milled on 0,05 mm dry, or under acetone. After adding Alu, mixed under acetone. As last is added ETN. Arises porridge, evaporate acetone and from it arises grain. On sieve 2x2 mm is separation for filling DDT mix grain 1-2 mm. For output segment is possible use pure ETN for highest brizance or same DDT mix, but from fine grain from separation procedure. DDT mix is drying to max. 40 Celsius on inert surface. ...... :cool:

......Dr.

nitro-genes - 25-1-2017 at 08:00

Interesting find, how does the finished composition burn when unconfined? Is there a certain mass where it can make DDT unconfined? Don't have much experience with permanganate, though didn't KMnO4 with alcohols produce hypergolic reaction? Have you tested how KMnO4 + erythitol (+ aluminium) behaves, or the finished composition containing ETN during storage, maybe with slight heating? Would also be interesting if one of the more stable manganese oxides could produce the same effect, maybe Mn2+ would also be effective in producing DDT....

NPED

Laboratory of Liptakov - 25-1-2017 at 10:51

Well, important question. Mix is stabile at 70 - 80 C (over melting point 61 C ) exposition 10 minute. Nothing changes. Longer time exposition was not tested. After cooling on 15 C arises middle solid agglomerates. On air the heap 0,5 g burned similarly speed is as nitrocellulose with sparkles effect. Pure ETN has self burning, but for this purpose slowly. Is thus necessary use next, different fuel - oxidizer. Usually 20 - 30 % adding. Basic catalyser (for DDT) and auxiliary fuel is Alu powder 10 - 15%. As auxiliary oxidizer is NH4ClO4 and now even KMnO4 10 - 15%. Simply: We needed basically ETN with his detonation properties. And some flashpowder, which force such mix into detonation in close solid space. It is all.
Experiences say, that oxygen balance near zero is you at nothing. Is needed try it. Estimate that will worked for example Pb304 + Al. And much next flashpowders, which are compatible with ETN. All components must be mixed near a molecular level. KMnO4 is very soluble in acetone same as ETN. NH4ClO4 not, but worked also. It is only research, Indeed, like almost everything here.... :cool:

Laboratory of Liptakov - 26-1-2017 at 12:18

But the last tests show that KMnO4 + ETN not compatible for prolonged periods. Respectively, all worked only 24 hours after mixing. During two days reduced function of DDT reliability of 50%. Well, thats research. Not all is perfect.
It is only find, observation of this phenomenon...... :cool:

....LL

nitro-genes - 26-1-2017 at 16:06

Understand it is just interest, was mainly curious how the composition would behave unconfined when accidentally ignited by friction or something.

Teflpon powder might also be interesting, or producing spherical particles of ETN in water, and coating them with the priming mix afterwards.

[Edited on 27-1-2017 by nitro-genes]

Laboratory of Liptakov - 27-1-2017 at 02:03

Well, important idea, coating ETN particles with some compatible and fast burning mixture. Maybe try it. Thanks, .... :cool:

Chisholm - 19-5-2017 at 07:55

What about a method to generate the primary explosive in-situ? Nichrome or other hot-wire resistor could be coated with a blob of lead solder and pressed up against picric or styphnic acid (perhaps with a thin coating of nitrocellulose lacquer over the solder to prevent direct contact until heat is applied).

The current would heat up the solder, which would then contact the picric or styphnic acid and form the lead salt, which should quickly explode from the heat.

Melgar - 23-6-2017 at 12:41

Wouldn't that fall outside the realm of being an NPED though? And wouldn't there be preferential conduction through the solder rather than the nichrome, essentially shorting it out?

Anyway, this thread gives me a certain amount of nostalgia. I remember back when not many users here believed me that this was happening with pure ETN, now there's all this research going into using this phenomenon to create safer high-explosive devices.

I'm not sure if anyone ever tried the thermite method, though it'd need to be ignited, probably with flash powder, in which case there wouldn't be a need for the thermite. What about a mixture in a high-boiling matrix that's solid initially, but melts, then boils due to the reaction heat? The matrix (when liquid at boiling point) would keep the reaction at a consistent temperature until it all boils away, at which point it'd go into thermal runaway, and heat up mostly uniformly. Of course, it'd be enclosed in a thin aluminum tube.

The only thing that I've actually done this with was a mixture of lithium metal and iodine that hadn't fully reacted. Adding water caused it to boil quite vigorously until the water was gone, at which point, the entire solid mass got red hot all at once and cracked the pyrex vial it was in, then caught fire with a brilliant red flame. Obviously this is nowhere near stable enough to initiate a detonation, but there are certainly plenty of similar reactions out there, I just can't think of any good ones off the top of my head.

Laboratory of Liptakov - 29-6-2017 at 12:17

Much attempts show, that solid cavity, especially for research is base of successful. Thus cavity cca 6 mm, from steel, wall 1,5 mm. And from this base is possible tested ETN with 20 50% of anything. Thermites, nitrocelluloses, perchlorates, magnesium, aluminium. And maybe of all entire together or only one from it.The basic a key is over pressure. And neither magic or incredible composition in paper tube. Dr.

Yes no magic...;-)

The harder the external container of the initiator...the higher the local confinement and thus a bubble of transitory higer density, higher deflagration/detonation pressure and faster velocity of deflagration/detonation --> thus easier D2D and detonation wave propagation to a secondary.

Even if the container only resist a few micro-seconds..once the shockwave at full power is passed through it is already initiating the secondary charge...not looking back to his original destroyed house ;-)

Has anyone heard about accidental detonation ETN from friction or impact?

[Edited on 22-12-2017 by Rocinante]

Laboratory of Liptakov - 1-1-2018 at 04:31

Best and most simple detonator is ETN + SADS. Because who has ETN has also HNO3. For SADS you need 10% HNO3 even only. Is Silver powder expensive for someone? Cigarettes and alcohol and your health are expensive. Silver not. I know that is not NPED theme, but using huge amount ETN in metal cavity, only for D2D effect is madness and not science.

Rocinante - 1-1-2018 at 04:54

paper or plastic, not metal.. just very long

I've heard that some poeple had problems with SADS not being stable inside the caps, leading to ignition failure.. is that true? Or how likely it is? I mean like chlorides from the tube...

The complexed Copper perchlorate that was a mix of TACP with a hexamine adduct TACP is an idea that might be improved by an alternative to hexamine.

Glycine (aminoacetic acid) complexes copper perchlorate.

Glycine also forms chelates and adducts and complex salts.

Methylamine can also displace and replace half the complex ammonia from a tetra ammonium copper perchlorate.

Glycine and Methylamine could either one be used similarly as is hexamine used to add a fuel component and adjust to oxygen balance the surplus oxygen of TACP alone.

Will there takes a few years, than some peoples will use some an substances from Rosco list. Again I am repeated here, but: Basic od system Berta is solid cavity, when output segment has high density. Usually 0,3g in diameter 6 mm. And starting segment with low density, grain stucture, where is insert hot wire. Usually 0,7g. As the plug, can be classic black powder 0,1g, glue, epoxy or even nothing. And works also. Basic EM is described above. Tetraamine copper perchlorate - TeACP with an compatabile fuel. HMTA, glycine or some substance from Rosco List. Results: 4 years of testing. 1500 detonators. And 10 entire fingers . ... :cool:

...Dr.

That list was from PHILOU

The glycine should form a compound with copper perchlorate

I see you already know about the glycinate complex

http://www.sciencemadness.org/talk/viewthread.php?tid=75315

I saw it mentioned somewhere that betaine, TMG also complexes copper perchlorate

I find listings for a tetrabetaine diperchlorate

Anyway the interesting possibility given the report that methylamine will displace half the ammonia from a tetra ammonium complexed copper, it may likewise be possible that other amines such as glycine, betaine, hexamine may also displace and replace part of the 4 complexing ammonias and give a mixed complex. Such a scheme could be used to adjust the oxygen balance of TACP where the necessary OB may be achieved by modifying some of the TACP with the higher amines which will provide added fuel.
