Priming composition which is sensitive to percussion and a method for preparing it

摘要

A priming composition with an elevated thermal stability, which is sensitive to percussion, is disclosed. The priming composition comprises a tetrazolic ring containing primary explosive and a sensitivity additive. The sensitivity additive comprises an oxidizing agent and a reducing agent. 40 to 95 weight percent of the priming composition is the primary explosive, 2.5 to 40 weight percent of the priming composition is the oxidizing agent and 2.5 to 40 weight percent of the priming composition is the reducing agent. The priming composition is applied to heads of percussion fuses.
