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?

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

It takes quite a lot to make an Ammonium nitrate mixture detonate. The famous ANFO is (was? My reference would be like a 1970 Dupont Blaster's Handbook) usually detonated with dynamite or special boosters containing many ounces of an intermediate-sensitivity explosive. A mixture of charcoal and AN ignited in a loose pile sort of smolders unimpressively. if you want to replace gunpowder, it needs to be tightly confined like in a gun barrel. If you want it to detonate, you either need a whole huge pile of it (cargo ships full are popular. See Texas City, Brest France, Red Sea) or a special booster, or you have to be exceedingly unlucky...

. From totse.com:
"AP was developed in the late 1880s as a replacement for black powder. It
is an intimate mixture of 85 percent ammonium nitrate and 15 percent char-
coal. ... It was extremly powerful, being on a par with double-based powders containing 30 percent nitroglycerine, and was virtually smokeless and flashless. ... when it was heated to moderate temperatures (32.1C), a change in the crystalline structure occured, causing the powder grains to crumble.
This would cause a drastic increase in the chamber pressure of guns using
this propellant, often causing burst tubes."
. Doesn't sound like DIY material to me.
