Abstract
An impact sensitive high temperature detonator is disclosed. The detonator comprises an initiator charge of lead azide next to a thin casing wall at the input end, and a mass of finely divided refractory material adjacent to the initiator charge. The detonator can be initiated by a rounded firing pin, which indents the casing wall without puncturing it. In the event of misfire, the casing will remain intact, which facilitates safe removal of the detonator.
