Publication number: 20080099112Abstract: This melt-pourable explosive composition shares explosive properties comparable to those of Tritonal and is melt-pourable and castable under conditions comparable to those of Tritonal, but experiences equal or less impact, shock, and thermal sensitivity and avoids the issues of toxicity associated with trinitrotoluene. The trinitrotoluene component of Tritonal is replaced with one or more mononitro aromatic and/or dinitro aromatic melt-pourable binders, such as dinitroanisole, which may be melt poured without presenting the toxicity drawbacks experienced with the use of TNT. The melt-pourable binder may also be combined with a processing aid selected from the group consisting of alkylnitroanilines and arylnitroanilines. The composition also includes oxidizer particles, which are preferably inorganic oxidizer particles, and a reactive metallic fuel, such as aluminum.Type: ApplicationFiled: November 9, 2005Publication date: May 1, 2008Inventors: Daniel W. Doll, Jami M. Hanks, Alan G. Allred, John B. Niles

Patent number: 7238336Abstract: A method of forming ?-alane. The method includes reacting aluminum trichloride and an alkali metal hydride to form an alane-ether complex solution. An aqueous diethyl ether solution is optionally added to the alane-ether complex solution to form a partially hydrolyzed ether/alane-ether complex solution. A solution of a first crystallization additive is added to the alane-ether complex solution or to the aqueous ether/alane-ether complex solution to form a crystallization solution. The first crystallization additive is selected from the group consisting of polystyrene, polybutadiene, polystyrene-co-polybutadiene, polyisoprene, poly-alpha-methylstyrene, polystyrene-co-polyindene, poly-alpha-pinene, and mixtures thereof. Optionally, a second crystallization additive is added to the crystallization solution.Type: GrantFiled: January 9, 2006Date of Patent: July 3, 2007Assignee: Alliant Techsystems Inc.Inventors: Gary K. Lund, Jami M. Hanks, Harold E Johnston

Publication number: 20040129356Abstract: A melt-cast explosive which shares comparable explosive properties to those of COMP B explosives and is melt-pourable and castable under conditions comparable to those of COMP B explosives, but experiences less impact, shock, and thermal sensitivity and avoids the issues of toxicity associated with COMP B. A fundamental and well-accepted component of COMP B, i.e., trinitrotoluene (TNT), is replaced with one or more mononitro-substituted or dinitro-substituted melt-cast binders, such as dinitroanisole, which can be melt-cast without presenting the toxicity drawbacks experienced with the use of TNT. The melt-cast binder can also be combined with a processing aid selected from the group consisting of alkylnitroanilines and arylnitroanilines. Preferably, the composition also includes coarse oxidizer particles and energetic filler in fine particulate form.Type: ApplicationFiled: August 22, 2003Publication date: July 8, 2004Inventors: Daniel W. Doll, Jami M. Hanks, Thomas K. Highsmith, Gary K. Lund
