AMMONIUM PICRATE History
In 1906, ammonium picrate is an explosive developed by Major Dunn.
It was used extensively by the United States Navy during World War I.
Though ammonium picrate was generally considered an insensitive substance, by 1911 the United States Army had abandoned its use in favor of other alternatives. The Navy, however, used it in armor-piercing artillery shells and projectiles, and in coastal defense.
Ammonium picrate typically did not detonate on striking heavy armor. Rather, the shell encasing it would penetrate the armor, after which the charge would be triggered by a fuse .
In 2008 caches of discarded ammonium picrate in remote locations were mistaken for rusty rocks at Cape Porcupine, Newfoundland and Labrador, Canada.

AMMONIUM PICRATE Uses
Ammonium picrate is used in armor-piercing shells as a bursting charge.
AMMONIUM PICRATE Production
Ammonium picrate (explosive D) is manufactured by the neutralization of a hot aqueous solution of picric acid (2,4,6-trinitrophenol) with aqueous ammonia.
AMMONIUM PICRATE Consensus Reports
