A safe and simple method for synthesizing insensitive nano-size cocrystals of high explosive materials such as HMX and Cl-20 by suspending the explosive materials in a nonsolvent solution and bead milling the solution.

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.

What is presented is a metal magnalium thermite pellet that is used to create heated gas. The metal magnalium thermite pellet is made to be inserted into the cutting apparatus that is used for cutting a conduit for oil, gas, mining, and underwater pressure sealed tool applications. To cut the conduit, the cutting apparatus radially projects a flow of heated gas from the internal surface of the conduit through to its external surface. The metal magnalium thermite pellet is also made to be inserted into the high power igniter that releasably secures to the cutting apparatus. Generally, the metal magnalium thermite pellet comprises a metal magnalium thermite composition that consists of between 1 to 44 percent magnalium alloy, 1 to 44 percent aluminum, 40 to 60 percent iron oxide, and 10 to 20 percent polytetrafluoroethylene.

What is presented is a combustible pellet for creating heated gas. The combustible pellet can be inserted into a cutting apparatus or a high power igniter or both. The combustible pellet is compacted to be resistant to mechanical damage, resistant to unintentional ignition, and free from a loose powdered form of combustible material when ignited in the cutting apparatus or the high power igniter. In certain instances, the combustible pellet is compacted to between 90 percent and 99 percent of its theoretical density. The combustible pellet may be capable of being transported separate from the cutting apparatus or the high power igniter or both. The combustible pellet may also be capable of being stored separate from the cutting apparatus or the high power igniter or both. The combustible pellet may comprise a circular cross-section and tubular length. The combustible pellet may comprise an axial hole.

A substantially cylindrical gas-generating pyrotechnical monolithic block has a thickness no lower than 10 mm, an equivalent diameter no lower than 10 mm, and a porosity lower than 5%; and a composition, given as weight percentages, which contains, for at least 94% of the weight thereof: +77.5% to 92.5% of guanidine nitrate, +5% to 10% of basic copper nitrate, and +2.5% to 12.5% of at least one inorganic titanate with a melting temperature higher than 2100 K.

Embodiments disclosed herein provide an Explosive Device Simulator (EDS). Embodiments of the Explosive Device Simulator may include two or more chemical components that are non-explosive when separated from each other within the EDS, but which form an explosive mixture or substance when combined. Because the individual chemical components are non-explosive, the Explosive Device Simulator may be stored, transported and handled safely for long periods of time and without increased security, protective measures, or special training. Further, the chemical components may be chosen such that the Explosive Device Simulator creates a realistic explosion (e.g. loud and bright), but which produces minimal concussive forces and is therefore safer to use as a training aid.

An in-situ process for synthesizing highly pyrophoric foam materials using metal and carbon precursors wherein the precursors serve as foaming and activating agents to disperse and lock nano-sized metal particles within a rigid porous carbon matrix. The resulting carbon matrix is also pyrophoric.
