OBSERVATIONS OF THE EFFECTS OF LOADING DENSITY ON THE INITIATION AND GROWTH OF DETONATION IN AZIDES

The ease with which lead azide builds from burning to detonation was measured for a number of different lots obtained from a variety of sources. The hot wire sensitivity of these various lead azides was also measured. The measurements show that dextrinated lead azide as presently specified is very v...

Description
Summary:The ease with which lead azide builds from burning to detonation was measured for a number of different lots obtained from a variety of sources. The hot wire sensitivity of these various lead azides was also measured. The measurements show that dextrinated lead azide as presently specified is very variable in its build up to detonation properties. Some lots of lead azide are particularly poor in making the transition from burning to detonation at commonly used loading pressures. The hot wire sensitivity of various lead azides is shown to increase with increased density and approach the sensitivity of the most sensitive hot wire explosives.
