Constant Current Initiation of Primary Explosives

Abstract

The constant current firing of diazodinitrophenol/potassium chlorate, lead styphnate, and lead azide was investigated. The temperature excursion of the bridgewire during constant current heating can be influenced by the density of the explosive, explosive phase changes, and heat generated by the explosive. Voltage inflection techniques indicate that diazodinitrophenol undergoes a phase change and is in a molten state at the time of ignition. The constant current time of initiation (and energy requirement for initiation) increase with loading density for normal lead styphnate and lead azide.
