THE EFFECT OF A GAS EXPLOSION ON SOLID EXPLOSIVES,

Abstract

Theoretical considerations affecting the conditions under which a gas explosion might initiate a solid explosive are discussed and experiments are described. The conclusion is reached, theoretically and experimentally, that the initiation of a solid explosive by a gas explosion is possible but only when the gas is under sufficient pressure. In the experiments, a small (15-20 mg) crystal of lead azide was initiated electrically by a thin wire; it in turn ignited the explosive gas in a glass tube (25 mm in diameter, 1.5 m long). A small quantity of the explosive being tested in the form of a solidified or large crystal was placed on a strip of iron in the middle of the tube. (Blasting gelatine, pentaerythritol tetranitrate, and picric acid were tried.) Heating some of the explosives to 100 degrees was tried but no detonation occurred. With secondary explosives, the theoretical calculation used were confirmed by the experiment. (Author)
