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.

CHP
Sure. Below the video's link to the study of Indian University:
http://www.researchgate.net/publication/5816481_Preparation_...
CHP is indicative abbreviation. And it is also a topic for another thread. Example The new energy materials - search. Next. Well, I am know about
mixture NiHN+Ag-xy. But this is even 2 primary together. AgCxy is total primary. It is not way for NPED. So much complicated produce, poisoned and
etc. Why do a lot of work?
ETN-Al-NC3. 75-15-10. Ratio as black powder.... No more primary, no more
tears.

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...

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......

hybride detonator
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.

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?
Rapopart’s Rules for critical commentary:
1. Attempt to re-express your target’s position so clearly, vividly and fairly that your target says: “Thanks, I wish I’d thought of putting it
that way.”
2. List any points of agreement (especially if they are not matters of general or widespread agreement).
3. Mention anything you have learned from your target.
4. Only then are you permitted to say so much as a word of rebuttal or criticism.

friction
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... Liptakov

NPED Detonator
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!

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.

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.
"Is this even science anymore?!"

Dr. Liptakov
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
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.

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...).
