Experiments were conducted to determine the effect of density on the required hot wire ignition energy and firing time of normal lead styphnate and barium styphnate. It was found that the ignition energy remained constant while the average ignition time decreased as the loading density was increased. It is postulated that changes in the thermal resistance between the wire and the explosive are responsible for the differences in the time of ignition. A faster transfer of energy to the explosive decreases the time the wire car act as an initiating stimulus when heated by a capacitor discharge and hence decreases the possibility of delayed ignitions.
