List of explosives more powerful than HMX
I want to propose creating a thread, or making this thread,
for educational purposes, a list of explosives possesing VOD higher than HMX, with density data included. I think a lot of
our members would appreciate (including myself) such a
comprehensive list - even if it's just for expanding our knowledge.
If you want to contribute, please reply with your entries for
the list (unless someone feels compentent enough to create
a full list themselves)
I hope you guys don't find this too K3WL

Thank you, I have never heard of TENGU before!

The list by Dornier is faulty, for example there is 0 way that a 1.79 or 1.74 g/cc explosive is more powerful than HMX, moreover some of his numbers
are just plain wrong.

"Hydroxylammonium 5-nitriminotetrazolate, 9300 m/s at 1.79 g/cc"
It is indeed somewhat true, although the density is actually even lower, at 1.78g/cc, but the VoD is also slightly lower, at 9240 m/s.
https://onlinelibrary.wiley.com/doi/full/10.1002/zaac.201100...
and the source for 3-Amino-3’-azido-4,4’-azoxyfurazan, 9400 m/s at 1.74 g/cc can be found here.
http://en.cnki.com.cn/Article_en/CJFDTotal-BGXB201301010.htm
It is rare that at those densities, an explosive can reach a VoD of over 9000m/s. The high volumetric gas produced, relatively perfect OB, and super
high enthalpy of formation did the trick.

They all claim pressures ~ 350 - 370 kbar, hence not more powerful than HMX - I'm familiar with Klapötke's work. Yes, VOD can shoot up. And remember,
Explo5 can crate 5 - 10 % errors.

Rocinante, please tell me which values you doubt and I will gladly provide you with a source (except for DTH, which is my own work).
I think you underestimate the importance of chemical composition since HMX lacks both the oxygen balance and enthalpy of formation that we see in new
experimental explosives.
For example, pure hydrogen azide reaches a measured detonation velocity of 7570 ±20 m/s at 1.127 g/cc, outperforming every single
explosive I have ever read about by almost 1000 m/s at that density.
The never-ending discussion about what makes an explosive "powerful" starts again... John paul specifically asked for VoD so that's what I provided.
Detonation pressure is more interesting in a few applications but is a weaker function the energy content of the explosive and a stronger function of
its density.
Since I've been writing thermochemical codes for more than five years now, I can tell you that modern code like newer versions of EXPLO5 and CHEETAH
do not produce 5-10% errors. They very rarely exceed 2% error in VoD for ideal explosives. We can safely assume that new, sensitive, high performing
materials are ideal.

How hard would it be for you to re-create a more accurate, up-to-date, metric version of PROPEP3?
I can give a new ingredient list too.

I meant 5 - 10 % for Pcj, not VoD, I'm shooting for Pcj not VoD in relation to HMX.

Good find Franklyn. I have had my eye on BNFF as a high performance melt castable explosive for a while, but I can't seem to find a good way to make
(or buy) malononitrile.

Note that in the dinitraminofurazan paper, they synthesize diaminofurazan without high temperature and pressure, just refluxing at 125C with urea as
dehydrating agent. The method is described more thoroughly in a 2014 paper by Zhang and Shreeve ( J. Am. Chem. Soc. 2014, 136, 4437) about
dinitraminoazoxyfurazan. If a high-pressure reactor is no longer a requirement for diaminofurazan, a lot of interesting research becomes much more
accessible.
