Abstract
A percussion primer compound for small arms, comprising a special metal such as zirconium as a reducing agent and a mixture of two oxygen carriers with oxidizing potentials of different magnitudes as oxidizing agent. The primer compound may be used in cartridge-type, small-caliber small arms such as is used for training purposes.
Claims9
A percussion primer compound for initiating a propellant charge in small arms, comprising the combination of a pulverulent, activated special metal reducing agent, an oxidizing agent comprising two oxygen carriers, each having a different oxidizing potential, at least one secondary explosive and at least one binder, said reducing agent, oxidizing agents, secondary explosive and at least one binder being combined in the absence of heavy metal compounds.
A method for the preparation of a percussion primer compound, comprising the steps of rinsing activated and temporarily stabilized zirconium powder with an organic solvent;
- and combining the zirconium powder with said oxygen carriers, at least one binder and at least one secondary explosive, and subsequently kneading, drying and pressing the resultant mass without the inclusion of any heavy metal compound to form a primer element.
