Development of heat resistant industrial explosives
Kenji Tanaka, Shinya Tanaka, and Tetsuya Sawada


When explosives are heated under acidic environment due to metal sulfide and sulfuric acidity, their decomposition temperature falls remarkably and decomposition reaction occurs quickly, and then explosives have the risk of the deflagration to the detonation transition. Heat resistant industrial explosives which can be used under condition of high temperature of 200 ℃ and acidic environment were studied. We developed the explosive composition consisted of ammonium perchlorateas oxidizer saturated hydrocarbon oil as fuel and binder, and calcium carbonate as decomposition inhibitor. The characteristics of this explosive composition show the heat resistance over 24 hours at 200 ℃ and the detonation velocity over 2,500 m s-1. This explosive composition has a cap - sensitivity at temperature higher than 80℃.
