  • Melt-castable nitramine binders for high energy compositions
    Patent number: 9890090
    Abstract: Provided is a melt-castable binder useful for stabilizing high energy explosive materials. A melt-castable nitramine binder has high energy in its own right yet is very insensitive to accidental detonation such as by shock or friction. The melt-castable nitramine binder is optionally combined with one or more high energy materials in the formation of an explosive composition with improved energy yield and safety and handling parameters relative to the high energy material alone.
    Type: Grant
    Filed: August 28, 2015
    Date of Patent: February 13, 2018
    Assignee: The United States of America as represented by the Secretary of the Army
    Inventors: Joseph Erik Banning, William Matthew Sherrill
  • Preparation of tetranitroglycoluril
    Patent number: 9695177
    Abstract: An improved method of preparing tetranitroglycoluril (TNGU) via the in situ decomposition of a nitrimino group with elimination of nitrogen without the use of dinitrogen pentoxide. The compound is useful as a high energy, high density explosive or propellant oxidizer.
    Type: Grant
    Filed: September 29, 2014
    Date of Patent: July 4, 2017
    Assignee: The United States of America as represented by the Secretary of the Army
    Inventors: William Matthew Sherrill, Eric Christopher Johnson
  • Combustible Triazine Combinations
    Publication number: 20170057883
    Abstract: Provided herein is a symmetric amino triazine for use as a fuel and ignition source in chemically initiated illuminates or igniters. 3-amino-1,2,4-triazine act as a fuel and generates enough heat on exposure to as little as one drop of one hundred percent nitric acid to spontaneously ignite.

  • Process for the production of speherical tetranitroglycouril
    Patent number: 9512127
    Abstract: A spherical morphology of the high explosive tetranitroglycoluril (TNGU) has been discovered. This new morphology exhibits approximately a twofold improvement in the response of the material to impact, more than a one and a half fold improvement in friction and the same high resistance to electrostatic discharge over non-spherical TNGU produced by other methods.
