Ammonium TRI-nitrate --- The old, new oxidizer
Hi there again*
Ammonium trinitrate - NH4NO3*2HNO3
This compound seems to be very interesting as an oxidizer - the only negative point seems to be, that it's caustic, but has an
interesting meltingpoint (27-29C) and seems to be +46.6% at Oxygen* 
US1997927
US3306789
Preview of an PDF (no freeware)
I think mixing around 10-20% of it into RDX (or other explosives with negative oxygen balance) could be very awsome  Especially because it seems that you can make cast-like explosive-blocks when
mixing the liquid ATN with warmed up "normal" explosives and then cool them down (US3306789)
Anyone has more informations about this compound? I used 3 searchengines but there are rarely informations (no density, VoD, leadblock-test,
frictiontest)
What do you guys think of this oxidizer?
*i used the HE calculator 1.0
*damn im so pissed of this board, i wrote nearly a dissertation about this compound and when i came to the sources-links i made a wrong
mouse-klick and ended up with a blank window....god damn

@Vlad
I think that this compound would make for highly unstable mixtures with most organic compound including RDX. It is likely to be at least partly
disassociated at room temperature and the free acid would tend to both hydrolysis many compounds and oxide them too. However, it may be a useful
substitute for absolute nitric acid where near anhydrous conditions are required for nitration, particularly as it may be more stable when stored
alone. I suspect that it will be somewhat hydroscopic though.
Interesting stuff never the less and I have not come across it before.

i'd say the acid might be problematic as it might make other compounds very unstable.. quite interesting stuff tho
about its properties.. i dont get how it can be caustic? typo? (:

Wow !! only if the melting point was just a bit higher !!!
Can i say it is a nitric acid hydrate of the salt AN ? Well, is it possible to make monohydrate ? or the Di-nitrate of ammonium ?

Sorry pal. I always ctl+c my stuff from time to time.
I guess that thing can be used where HNO3 is. For example if it can dissolve some stable negative OB material may be TNB?
NO2-physically unstable/freezes and evaporates very easy
HNO3-chemically unstable/corrodes things and decomposes
ATN-kinda best of both? May be comparable to nitroform of TNM?

i havent much chemical skills but it seems to compare this with coppersulphate pentahydrate (CuSO4*5H2O to NH4NO3*2HNO3)...it SEEMS not to be a
"trinitrate" the way we know "trinitrates" normally.
I have been searching for the Di-Nitrate too, espechially because of the caustic propertie, but i couldnt find serious sources...most sources wrote
abour "-Trinitrate" and shown the structure with nitrogroups - so they probable thought ADN (ammonium dinitramide)

well....i think i read about it , but dont know where.
But isnt even NH4NO3 slighty caustic - bechause its a salt of the damn nitric acid....so how on earth (c/w)ouldnt the Trinitrate not be
caustic/agressive to other materials...dont know...maybe i'm wrong at this point 
i would really wish it where not, because the other properties of ATN are awsome

Well true for an smoke-less oxdizier, but i find Nitro-carbons better, for some reason. It have around +50% oxygen.

well...no doubt, this stuff (nitrocarbons) is strong as hell, BUT im searching for cheap/easy-to-get-and-make stuff...
really strong explosives are most times too expensive or theres a need for too exotic chemicals...
im pretty sure, even if i had the skill/knowledge, i would need some high end laboratory to make this stuff...

Two words , strongly hygroscopic and strongly acidic
Not much good outside of Antartica.

Sounds like an unstable compound to me, which for most practical purposes can be considered like a 1 : 2 molar ratio mix of ammonium nitrate and
nitric acid. It apparently can be made by dissolving 1 mole of dry ammonium nitrate in just over 2 moles of white fuming nitric acid at a temperature
of well over 30 C and then cooling down the solution. It solidifies, the mix has stoichiometry NH4NO3.2HNO3 and is somewhat humid due to adhering free
HNO3.
I expect this to be a nasty fuming and very corrosive wet solid, nothing you want to play with in pyrotechnic applications. A lab-curiousity, nothing
more.

"Caustic" means that it will burn or corrode organic tissue- it does not necessarily mean that it's strongly basic. Nitric acid *is* pretty
corrosive, you know.
Please remember: "Filtrate" is not a verb.
Write up your lab reports the way your instructor wants them, not the way your ex-instructor wants them.
