Ammonpulver (explosive)

hey, i was wondering if anyone has any experience with it. it is ammonium nitrate and charcoal. i hear it is hard to ignite? does anyone know the ratio?

Ammonpulver is a German name given to a low explosive fuel oxidizer mix containing solely ammonium nitrate and charcoal, this composition contains an enormous amount of energy for a simple physical mix with power close to that of double base powder containing a considerable amount of nitroglycerin.
However even though it contains the energy, its burn rate is slow and therefore is not suitable for bursting explosives.
Possible uses for this explosive are big bore gun propellant and rocket fuel. It has advantages over black powder in this role because of the increased energy, flashless and emits only a small amount of blueish smoke.
To make this composition -
finely powder ammonium nitrate and willow charcoal to as finer consistency as possible (finer the faster and more efficient) and mix to a ratio of 8 parts AN to 2 parts charcoal.
Once thoroughly mixed add methylated spirits until it clings together like thick mud.
strain this paste between two flat surfaces and leave to dry.. If your in the colder wetter months of the year don't bother as it will never dry.
Once hard, break it up into small granules and its ready to use.

Taken from: Arsenal.html...but I do not know how reliable it is.
that is very interesting as im looking for a mixture for model rocket fuel but do not have easy access to potash but have big access to ammonium nitrate as farm fertiliser, this is the first recipe i have found but the link you have kindly provided is no longer in use, any chance of more info on this mix would be greatly appreciated...thanks.
This is what I found concerning NH4NO3 :  Sites containing this information seem to be shutting down, or are being shut down, in droves, but HERE is one site that has a bit more detail on NH4NO3
thanks i'll check it out.

that's how it is AN is just an oxydiser, it's not a fuel and it needs to be thoroughly mixed with it's fuel to ignite

Just a note: Unlike saltpeter-based explosives, those based on ammonium nitrate detonate. That is, they consume their fuel in millionths of a second so that the entire reaction is complete before the gas has a chance to expand. Consequently a shock wave is generated which shatters anything nearby including the container. Such explosives cannot be used as propellants or gunpowders as they will destroy the rocket, gun, or cannon. The principle use of these explosives is in blasting, either for mining or for construction.

not AP it slower then BP the fact that it contains AN doesn't make it a high explosive

. Methylated spirits = denatured alcohol. Should be able to find it at just about any paint/hardware store.
Ok, when I read Kruser's post, I thought I saw Mentholated spirits and I just was not familiar with them. (rubs eyes......need new glasses)

Minty fresh ! *sigh*

I don't know. It may or may not dissolve the nitrates (or whatever it does there) before evaporating. *sorry I am not of much more help*
