  • Patent number: 8540828
    Abstract: A primer composition that includes red phosphorus having an acid scavenger and a polymer thereon. The primer composition includes at least one other component that is substantially free of lead. The other component is at least one oxidizer, or at least one oxidizer and at least one of at least one secondary explosive composition and at least one energetic binder. The primer composition optionally includes at least one element having an ionic charge to ionic radius ratio of 4 or of 8, such as magnesium, zirconium, aluminum, silicon, titanium, tungsten, alloys thereof, and combinations thereof. The red phosphorus and the at least one oxidizer are present in the primer composition at approximately stoichiometric amounts. An ordnance element including the primer composition is also disclosed.
    Type: Grant
    Filed: August 19, 2008
    Date of Patent: September 24, 2013
    Assignee: Alliant Techsystems Inc.

  • Patent number: 8524018
    Abstract: 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.
