Provided herein are VIS-IR powders comprising tin which show significantly higher visual intensity, reduced reaction temperature and particle temperature during and after oxidation reaction in air, and improved resistance to clumping when compared to comparable powders without tin. Methods of preparation of said VIS-IR powders are also disclosed.

Disclosed herein are energetic compositions and methods of making thereof. A composition includes perchlorate or nitrate containing oxidizer particles, a polymeric binder, and a borylated ferrocene derivative bonding agent bonded to a surface of at least a portion the perchlorate or nitrate containing oxidizer particles to form a Lewis complex.

A high strength engineered reactive matrix composite that includes a core material and a reactive binder matrix combined in high volumes and with controlled spacing and distribution to produce both high strength and controlled reactivity. The engineered reactive matrix composite includes a repeating metal, ceramic, or composite particle core material and a reactive binder/matrix, and wherein the reactive/matrix binder is distributed relatively homogeneously around the core particles, and wherein the reactivity of the reactive binder/matrix is engineered by controlling the relative chemistry and interfacial surface area of the reactive components. These reactive materials are useful for oil and gas completions and well stimulation processes, enhanced oil and gas recovery operations, as well as in defensive and mining applications requiring high energy density and good mechanical properties.

The present invention is directed to composite particles that react with a small and adjustable input energy. The ignition threshold depends primarily upon reactant spacing and chemistry, not overall particle size. Combustion properties, such as burn duration and temperature, are controlled by adjusting particle size or reactant composition. The best performance is achieved by selecting reactants with strong intermetallic formation reaction and that combust in different phases (condensed vs gaseous). These particles are fabricated by various methods, including physical vapor deposition, or ball milling. The concept of purposefully decoupling ignition and combustion properties by fabricating particles where ignition is determined by reactant spacing and/or composition and combustion is determined by adjusting particle size and/or composition is described. Combinations of specific reactants, such as Al, Zr, Ti, Mo, Mg, B, Li, etc. exhibit dual-phase combustion, and/or enhance combustion through prevention of terminating species. Ternary additions are used to form gaseous species.

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.
