Ammunition primer composition for small arms

摘要

A heavy-metal free primer composition consisting essentially of potassium dinitrobenzofuroxane as a primary explosive, diazodinitrophenol as a secondary sensitization explosive, and an inert sensitizer is disclosed. The preferred mix is comprised of 50% of potassium dinitrobenzofuroxane, 30% of diazodinitrophenol and 20% of ceramics powder as the inert sensitizer. This composition has sufficient sensitivity, good ballistic properties for all types of cartridges and very strong stability in high temperature and high humidity conditions.
