Abstract

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.
