Ammonpulver = ammonium nitrate

There have also been interesting and promising attempts to use ammonium nitrate as a component of high explosives. Particularly noteworthy are the experiments in which potassium nitrate in blackpowder is completely or partially replaced by ammonium nitrate to improve brisance. This led to the ammonium nitrate mixtures, Ammonpulver M90 and M96, 15/85 mm. They were employed in Austria for filling shells at the end of the nineteenth century but were not used for long, due to the difficulty of detonating them. 

Propellent powder made from ammonium nitrate is about as powerful as smokeless powder and has long had a limited use for military purposes, particularly in Germany and Austria. The Austrian army used Ammonpulver, among others, during the first World War, and it is possible that the powder is now, or may be at any time, in use.
