Initiating element for nonprimary explosive detonators

摘要

An initiating element of non-primary explosive type comp­rising a confinement containing secondary explosive, having a first end adapted for ignition of the secondary explosive by igniting means, optionally via delay and flame-conducting py­rotechnic compositions, a second end adapted for delivering a detonation impuls and a intermediate portion in which the se­condary explosive upon ignition is able to undergo a deflagra­tion to detonation transition. At least a part of the seconda­ry explosive is modified to give increased reaction rates at low pressures.
