Title: Ignition and initiation of potassium picrate and potassium picrate/explosives mixtures

Abstract

Potassium picrate (KP) and KP blended with PETN or HMX can be ignited by a hot wire. Maximum gas pressure generation occurs in several milliseconds and is about 0.3 GPa in a volume of 1 cm/sup 3/. The shock from detonating PETN initiates small, brass-confined pressings of KP to steady detonation velocities of 3.5 to 5.5 km/s in the density range 1.0 to 1.6 Mg/m/sup 3/. KP mixes can be employed as deflagrating donor mixtures in 2 types of electric detonators. In one the high pressure deflagration drives a stress wave into an explosive in which the deflagration is transformed into a detonation. In the other the high pressure accelerates a flying plate which initiates detonation in an acceptor explosive upon impact.
