A primer composition that includes stabilized, encapsulated red phosphorus, at least one oxidizer, at least one secondary explosive composition, at least one light metal, and at least one acid resistant binder. The stabilized, encapsulated red phosphorus may include particles of red phosphorus, a metal oxide coating, and a polymer layer. The metal oxide coating may be a coating of aluminum hydroxide, bismuth hydroxide, cadmium hydroxide, cerium hydroxide, chromium hydroxide, germanium hydroxide, magnesium hydroxide, manganese hydroxide, niobium hydroxide, silicon hydroxide, tin hydroxide, titanium hydroxide, zinc hydroxide, zirconium hydroxide, or mixtures thereof. The polymer layer may be a layer of epoxy resin, melamine resin, phenol formaldehyde resin, polyurethane resin, or mixtures thereof. A percussion cap primer that includes the primer composition, a tertiary explosive composition, and a cup is also disclosed, as are ordnance devices including the primer composition.
A percussion primer comprising a primer composition, a tertiary explosive composition, and a cup, wherein the primer composition comprises a stabilized, encapsulated red phosphorus, at least one oxidizer, at least one secondary explosive composition, and at least one light metal, the stabilized, encapsulated red phosphorus comprising from approximately 10% by weight to 28% by weight of a total weight of the primer composition, the at least one oxidizer comprising from approximately 30% by weight to approximately 80% by weight of the total weight of the primer composition, the at least one secondary explosive composition comprising from approximately 1% by weight to approximately 10% by weight of the total weight of the primer composition, and the at least one light metal comprising from approximately 1% by weight to approximately 10% by weight of the total weight of the primer composition.
An ordnance device, comprising:
