Flumen amazing find!

Don't take my word for it: https://reader.elsevier.com/reader/sd/pii/S0304389418312597?...


Fulmen. This forum can’t thank you enough for this find! Wow imagine if 5-10 percent micron aluminum was mixed in too... I suspected molten ETN was more sensitive.. but not this much.

Agreed. Walk away... it’s just not worth the risk... and that’s assuming PURE ETN

We really need to find a good liquid or castible explosive for the armature. With 3D printing, we can come up with some pretty crazy container shapes. So I see this as a growing need.

Nitromethane is great but lacks the VOD and density. Maybe LL’s formulation of DEG and sodium perchlorate?? Didn’t that have a VOD of over 7500 m/s? Cheap too..

Tests shows, that DEG+NaP has incredible damage power. Primary is very good brizancion, and secondary is it effect of evaporation of water. Which can destroy thick metal plate to a long distance from epicentrum. Really longer distance than ETN at same charge. For testing broken any tree is DEG+NaP much efficience and much cheapest than molecular nitro - some....:cool:...LL

Since I can only assume that DEG is your acronym for nitroglycol, why would anyone in their right mind want to mix zero OB nitroglycol with an oxygen-rich, hopelessly hygroscopic salt?

Not, DEG is Di Ethylene Glycol. With Sodium perchlorate (NaP) works also ethyleneglycol EG, or triethyleneglycol TEG. But best properties are just with DEG. = Dyno Nobel = Patents: https://patents.google.com/patent/US5665935

Perchlorates looks very promising. I have not seen much research on CLO4 salts etc but they look more suitable for amateurs. There is no need for concentrated acids, difficult to buy chems e.t.c. just like nitro-nitrates. Also CLO4 salts can be produced cheaply in huge amounts.

Ooops! Pardon my brainfart, LL ─ it's not even like I'm unfamiliar with di-ethylene glycol...

Acronym derangement syndrome, I guess?

LL. I have noticed sodium perchlorate is becoming much harder to source. I can’t find it and I am in the good old US if A.

Also... LL what would the performance be with lithium perchlorate :)!?? How about this. 10-15 percent 3 micron PTFE, lithium perchlorate and DEG... that way the lithium does not go to waste!! Fluorine is underrated.
