For sure, especially if you have seen alibaba prices 
But those 7.5g, turned into a nitrotetrazolate primary would last...if you have a secondary in mind, not so much.

Engager stated 0.00689 mol NaNTZ. The molar weight of NaCN5O2*2H2O is 173.06 g/mol. 0.00689 mol*173.06 g/mol = 1.192
g.
The molar ratio of the copper complex to sodium nitrotetrazolate is 2:1, which I don't really see the point of. But I think you should follow
Engager's instructions.

Well I calculated the same tnx: 3.5 grams of carbonato triammine copper(II) nitrate for every 1.91 grams of NANTZ.
With BNCP it is the opposite: 1.4 grams of cobalt stuff for every 2.6 grams of NANTZ.
Since NANTZ is harder to make, maybe the copperstuff is better variant to make! You need a lot less of NANTZ!

I made BNCP and NaCUNTZ. I was able to set off BNCP with a relatively simple primer such as mealpowder. However, NaCUNTZ seems to need a hotter
primer. I think I can get 5/10 in my blastingcaps with NaCUNTZ. So, I am looking for a decent priming composition. I have tried 80 leadtetroxide/20
silicon and this one burns veryy fast (flashpowder like). Mayb you guys have some suggestions for a very hot primining composition.

I synthesised a small amount of C2H4N14 bis-diazotetrazolylhydrazine, or as I prefer to call it,
ditetrazolylhexaazadiene.
When I dripped almost colourless diazotetrazole solution into hydrazinium chloride solution, it turned pink and then a fluffy yellow precipitate
formed. It hydrolyzed again before I could vacuum filter it. After a few days tiny dense grains of a yellow compound had precipitated. A single of
those grains, approx 50 micrograms detonates violently enough to rip a hole though aluminium foil when heated slowly. Still, it's not the unequivocal
primary I though it would be. A few milligrams only puff and spread out the pile when ignited. Strongly pressed it is extremely brisant.
Density was calculated to approx 1.75 g/cc by group addition method, similar to 5-azidotetrazole (1.72 g/cc), 1-diazidocarbamoyl-5-azidotetrazole
(1.72 g/cc) and 1,1'-azobis(tetrazole) (1.77 g/cc). Enthalpy of formation is most likely between +1300 and +1500 kJ/mol based on its structure and
similar compounds. This gives it a detonation velocity of around 9300 m/s.
Here's my video about it: https://www.youtube.com/watch?v=qVZT5aR3ih0

guanazole reaction revisited
From about 7 years ago to again about 4 years ago and later a couple of years ago the subject of guanazole has received some attention. This post by
Engager links back to the original discussion in another thread which is continued here in this thread.
http://www.sciencemadness.org/talk/viewthread.php?tid=8144&a...
I have some additional information snippets which are tending to support my earlier idea of synthesizing guanazole using the patent process of
US2648671 which is reaction of molar equivalents of cyanoguanidine with hydrazine dihydrochloride in aqueous suspension to provide a quantitative
yield of guanazole.
I still speculate it may be possible to proceed without isolation of the guanazole to diazotize and produce the dinitro derivative,
or to produce the 50/50 mixture of the dinitro derivative with 5-nitrotetrazole via Sandmeyer reaction condition.
I think this may possibly be the easiest route to a tetrazole or more precisely to a mixture or possible double salt that is 50% 5-nitrotetrazole with
the other 50% being 3,5-Dinitro-1,2,4-triazole according to the method of US3054800.
The best strategy for accomplishing this synthetic route is not yet identified and there would seem to be variations on the approach possible, which
could involve isolation of a guanazole derivative as an intermediate, either a guanazole double salt complex with copper sulfate, or if it exists even
better would be a double salt complex of guanazole with copper nitrate.
An additional possibility is the formation of a guanazole nitroso derivative which may be a not previously identified intermediate for either
3,5-Dinitro-1,2,4-triazole, or possibly an intermediate in the patent process leading to the 50/50 mixed product. I believe that a possible isolation
of the copper salt or ammonium complex copper salt, or double salt could be done. Or it may be possible to separate the 50/50 mixture into its
components, depending upon how the process is done.
Does anyone have any information as to whether or not guanazole forms a double salt with copper nitrate as does form with copper sulfate? Further,
does anyone have information about the nitroso derivative of guanazole, which would possibly be guanazole oxime? See the article attached page 518.
Also attached is an abstract for a Russian article which is not available online, but which may be helpful.
I am still studying and reviewing what are available references so I am sharing what I accumulate on this potentially useful synthetic route and its
possible products. The silver and the copper salts would seem to be of interest. And of course there are many possible double salts not yet
identified.

I tried recently it. With the method Rosco Bodine posted here http://www.sciencemadness.org/talk/viewthread.php?tid=8144&a...
The synthesis worked just fine even when I haven't reach the temp. of 100°C at the end (had about 80°C)
My DBX-1 was first reddish but finally after it was fully dry it also gets its almost black apperance. These chunks were
difficult to powder but possible. I broke them up carefully. Finally I got the rusty colour stated in the literature. Also much more flame sensitiv
and gives a greenish flame when ignited.

I synthetised 5-Aminotetrazole two times now.
The first time small scale with the method posted by Engager. The yield was ok and the product was very pure.
But now I scaled it up a little bit.
Approximately 10g Aminoguanidin bicarbonat ; 200ml 15% sulfuric acid ; 10g Nano2
and much sodium carbonate for the PH.
The problem is that I had a massiv yield of about 100g. I suppose that this is too good to be true
After cooling there were only crystals left in the beaker no more fluid, so I guess that all impurities also crystallized.
The Ph of my "5-Aminotetrazole" is neutral.
Is someone able to explain this yield?
Does someone know how to remove the sodium carbonat or sodium sulfat (Cause I neutralized with sulfuric acid) in my 5-Aminotetrazole. Suitable
Recrystallization?
(Video to this method: https://www.youtube.com/watch?v=oTjgHo-EdXY) he also had a massiv yield but I halved the amount of chemicals used.
Thank you

@Mr.Greenix it sounds like you have much sodium sulphate hydrate in there! 5-aminotetrazole crystallises as the monohydrate so you should get about
7.5g at 100% yield but you usually only get about 75% with the Thiele method.
Try treating the product with dilute HCl to ensure that it is the free tetrazole derivative, then leach with water until you have got rid of most of
the sodium salts and then recrystallise from water. 5-aminotetrazole is very soluble in hot water but sparingly soluble in cold water and salt
solutions so the recovery during recrystallisation is usually good.
By the way, always allow the filtrate to stand for several days or a week in contact with a few grains of the initial product and also stir
occasionally making sure you rub the vessel walls occasionally. 5-aminotetrazole has a terrible tendency to supersaturate.
PS just because somebody makes a youtube video it doesn't mean they know what they are doing!

The first link in Rosco's post shows its properties very well, but I'll provide some more information here.
Ditetetrazolylhexaazadiene is described in Engager's Energetic Derivatives of Tetrazole with the name bisdiazotetrazolylhydrazine and
briefly in Fedoroff. It's synthesised by mixing diazotetrazole solution with a solution of hydrazinium chloride and sodium acetate. My product
immediately dissolved/decomposed after forming though, probably due to too basic conditions. Replacing the hydrazinium chloride with hydrazine sulfate
worked well, and sodium acetate buffer doesn't seem necessary, although the product is whiter without.
The product seems stable after drying but rapidly dissolves in basic solutions to give a strongly yellow solution. It hydrolyses slowly in water to
give gas bubbles (nitrogen?) and 5-azidotetrazole. My product is stable in acidic solutions though.
Now comes the fun part: it's more explosive than anyone has probably ever dreamt of. My calculated performance at the measured density 1.8
g/cm3 is 9700 m/s and 420 kbar.
In addition, it's critical diameter is microscopic. I played around with tiny grains under a microscope, trying to make as small flakes as possible. I
got an 18 micron thick flake, approximately 0.4 micrograms, to detonate (it put a dent in the aluminium foil).
This performance is not without downsides of course; it is exceptionally sensitive. Filter papers covered with ditetetrazolylhexaazadiene explode if
ripped (something I discovered without protection...) Light tapping with a hammer sets it off, as does pressing. More videos will come in the future!

Regarding the aminoguandine bicarbonate precursor for aminotetrazole
A point of interest is a second independent confirmation regarding the pyrolitic decomposition of calcium cyanurate to pure calcium cyanamide. I
think Davin first reported this does in fact work even as a "campfire" cyanamide produced in the hot coals of a wood fire kind of adapted process so
long as there is venting of the byproduct gases from the heated to orange heat container allowed, but not allowing air ingress into the reaction
mixture.
It looks like maybe a hacksaw cut was made to defeat the sealing of the threads and allow controlled venting for the "bomb" used for the pyrolysis
which is good technique. A small press fit "freeze plug" type of safety overpressure blowout plug is a good idea also in the top end cap for a
reactor like this in case venting is ever obstructed to prevent pressure buildup in the reactor. Probably a good easy safety vent providing a "gravity
seal" would be to use a 3/8" clevis pin dropped into a 3/8" hole drilled into the end cap, with the loose seal at the shoulder being sufficient. The
shaft of the clevis pin could be scored with a diagonal groove cut using a hacksaw, and if pressure from venting raised the clevis pin to the cut
groove it should regulate there by gravity like a pressure cooker regulator, and function as a loosely fitted check valve and regulator.

Having just synthesised five grams, its safe to say that I will never touch it again. One flake on the floor nearky gave me a heart attack. 4 grams
contained with aluminium foil within a plastic bag lit at the bottom of the water bottle absolutely shred it. Despite being able to isolate ~10 micron
flakes, it has yet to not detonate...

Ok so it has been quite a journey from pool chemicals, urea, sodium bicarbonate and hydroxide , ammonia, hydrochloric, sulfuric, nitric acids copper
sulfate sodium nitrite and anything else I had forgotten but finally I got to make some of the copper nitrotetroazolate primary I had aimed for.
All components were OTC or made from OTC components except the 70% nitric acid( which could easily be synthesised OTC anyway) including the ammonia
which I made from NaOH and ammonium sulfate, the hydrazine, the cyanamide ( my method was shown in video above) which all together formed the basis of
the 5-ATZ and finally the CuNTZ.
Basically I had followed Engagers work here. It's his legacy here it would seem...
I must say though I'm pretty impressed by this compound although it is not the best initiator made from the 5-ATZ and really want to attempt the
silver variant and the Mercury variant especially. This particular salt gave me no troubles synthesising it and I was expecting the micro explosions I
had read about but luckily for me none happened. The only problems were the NOx fuming and thevery slow filtering of the ultra fine green mud.
It seems to have a tiny critical diameter and minute grains go off with a crack when heated on foil putting pin holes in it but with confinement in
foil and heated it gives a pretty loud report and sends silver foil confetti flying. I want to test it a little more but so far I can see why
primaries based on 5-ATZ and its salts are of interest as green energetic materials.

Oh my God. On roofs I see Neon - Cu NTZ compounds! Is not necessary huge a complication of synthesis. Much easily is scratching from the roof. Without

NeonPulse, is that Cu(NTZ)2 or is it the acid copper nitrotetrazole salt? Because that one is supposed to be very
sensitive.
Liptakov, I climbed my local church's roof and found this:
It turned out to be copper(II) 5-azidotetrazolate though! Be careful!

It's the acid copper salt. It's colour is much paler than the picture portrayed but the camera seem to get it right. It would be much better if it
had a higher density like crystals rather than the fine fine powder. It doesn't seem overly sensitive but a lot of care is still taken while handling
the dry product. Once it had been dried for weighing I have sprayed a mist of water to dampen it and put it in a container till it's needed.
Is it right that being stored underwater will slowly decompose it? I think I read that in some PowerPoint presentation about green initiators some
time ago.
Wet storage is much preferred to missing fingers and I can easily see a small amount doing a lot of damage to a careless handler.
I know it seemed overly complicated but it's not really.Basically I wanted to see if this could be done using all OTC chemicals and it seems that with
a bit of work and effort it can. However for all that work put in over a few weekends the end result was only a few grams of the green stuff. But
that's enough since a little bit goes s long way.Most people would probably say it's hardly worth the time but hey, I think it's time well spent.
I'll Give the photo another go:
