A technique for forming an energetic ink is provided. The technique includes forming a non-reactive layer by disposing a composite ink on a substrate, the composite ink including a polymer binder that is solvent-permeable and porous fuel particles (e.g. porous silicon particles). Mixing, printing, casting, assembling, or otherwise handling the inert composite can occur while it remains non-reactive. Subsequently, the technique can then include depositing a liquid solution of solid oxidizer onto the non-reactive layer, which can permeate the binder and impregnate the porous fuel particles with a solid oxidizer, activating the composite ink. In this manner, components with the composite ink can be partially and safely fabricated/assembled while the ink is inert, and the ink can then be activated at a later point in a manufacturing process.

The present invention generally concerns decomposing a ternary metal hydride to isolate nanoparticles to use in a fuel grain. More specifically, the present invention harnesses increased energy densities from two distinct nanoparticles isolated by a precise decomposition of LiAlH.sub.4. The singular material is air stable and is a nanocomposite of Li.sub.3AlH.sub.6 nanoparticles, elemental Al nanoparticles, an amount of Ti metal, and a nanoscale organic layer. We call this nanocomposite nMx, which protects and preserves the high energy densities of the core metals isolated from the controlled reaction, making the nanoparticles safe to handle in air. The narrow distribution of nanoparticles has no byproducts or phase transitions that decrease energy output. The unique burning characteristics of nMx enhance the combustion of solid propellant formulations compatible with solid or hybrid rocket motors, where fuel grains are cast, pressed, or 3D printed with nMx powder, a polymeric binder, or optional additives.

A multi-purpose putty product usable as a lamp fuel, first aid medication, water proofing agent, water sealant, and UV responsive marker is shown and described. The putty component may include waxes, oils, pine gum rosin, powdered metallic thermite fuel, and cotton fibers. Optionally, the putty may include a colorant and plant essential oil as an odorant. The putty may be provided in kit form, with a receptacle and closure, and a tool enabling putty product in the receptacle to be exposed and held erect for service as a wick while burning.

An igniter composition has (i) a source of copper selected from basic copper nitrate, copper oxide, copper hydroxide, and/or copper complex of guanylurea nitrate, (ii) one or more oxidizers, (iii) a binder selected from guanidine nitrate and/or guanylurea nitrate, and (iv) an inorganic fuel comprising an elemental metal or metal hydride selected from the group consisting of: titanium, silicon, aluminum, magnesium, iron, and combinations thereof. The igniter composition may be substantially free of boron or contain minimal amounts of boron. A minimum flame temperature at combustion (T.sub.c) of about 2300K (2,027 C.). Such a mixture may be spray dried to form a powder that is compacted to form a solid igniter composition, such as a pellet or grain. The mixture that is spray dried may have a heat of explosion (HEX) of about 1,000 calories per gram (cal/g). Inorganic fuel can then be added to the spray-dried powder.
