1. A primer composition comprising:
- at least one non-metallic percussion sensitive explosive material selected from the class consisting of diazo, triazole, and tetrazole compounds;
at least one fuel source;
manganese dioxide, and a secondary oxidizer selected from the class consisting of strontium peroxide and zinc peroxide, said secondary oxidizer being present in amount not greater by weight than the manganese dioxide.

Abstract
A primer composition using manganese dioxide as the predominant oxidizer is disclosed. The manganese dioxide oxidizer is combined with a fuel source and non-metallic initiating explosive material. Various diazo, triazole, or tetrazole compounds may be used as non-metallic initiating explosives, although diazodinitrophenol is preferred. The combustion by-products of the invention do not include toxic oxides of lead, barium, or mercury. The invention therefore provides distinct safety and environmental advantages.

6. A primer composition comprising about 20-40 percent non-metallic primary explosive material selected from the class consisting of diazo, triazole, and tetrazole compounds, about 0-10 percent sensitizer material, about 15-30 percent fuel material, about 0-50 percent non-metallic secondary explosive, about 10-50 percent manganese dioxide, about 0-20 percent secondary oxidizer selected from the class consisting of zinc peroxide and strontium peroxide, and about 0-2 percent binder material, all of said percentages by weight of said composition, said secondary oxidizer being present in amount not greater than said manganese dioxide.
