Abstract
A primer for small arms ammunition including a primary explosive and an oxidizer system containing bismuth oxide is provided. A method of forming the primer and a small arms ammunition cartridge also is provided. The oxidizer system can be non-hygroscopic and non-toxic. The primer can include reducing agents or fuels, sensitizers, binders and gas producing agents.
Claims27
A priming mixture for small arms ammunition comprising:
- a primary explosive selected from the group consisting of:
- trinitroresorcinol, mercury fulminate, lead azide, lead styphnate, silver azide, diazodinitrophenol, tetrazene, potassium dinitrobenzofuroxane, heavy metal salts of 5-nitrotetrazole, and any combination thereof;
- a gas producing agent of about 5% to about 20% by weight;
- a fuel;
- and
- a non-hygroscopic, non-corrosive oxidizer system comprising bismuth oxide, wherein the bismuth oxide comprises at least 15% by weight of the priming mixture.
A priming mixture for small arms ammunition comprising:
- about 20% to about 70% by weight of a primary explosive selected from the group consisting of:
- trinitroresorcinol, mercury fulminate, lead azide, lead styphnate, silver azide, diazodinitrophenol, tetrazene, potassium dinitrobenzofuroxane, heavy metal salts of 5-nitrotetrazole, and any combination thereof;
- about 10% to about 70% by weight of an oxidizer system comprising bismuth oxide, wherein the bismuth oxide comprises at least 15% by weight of the priming mixture;
- about 5% to about 25% by weight of a gas producing agent;
- about 0% to about 20% by weight of a sensitizer;
- and,
- about 5% to about 20% by weight of a reducing agent.
A priming mixture for small arms ammunition comprising:
- about 25% to about 50% by weight of a primary explosive selected from the group consisting of:
- trinitroresorcinol, mercury fulminate, lead azide, lead styphnate, silver azide, diazodinitrophenol, tetrazene, potassium dinitrobenzofuroxane, heavy metal salts of 5-nitrotetrazole, and any combination thereof;
- a gas producing agent of about 5% to about 15% by weight;
- and,
- about 25% to about 55% by weight of an oxidizer system comprising bismuth oxide, wherein the bismuth oxide comprises at least 15% by weight of the priming mixture.
The priming mixture of claim of 17, wherein the gas producing agent is selected from pentaerythritol tetranitrate, trinitrotoluene, or combinations thereof.
