Abstract: A formulation and methods for making high energy organic fuels that incorporate suspended metal particles with metal particle sized ranging from 33 nm to 5 micron. The hybrid organic fuels contain superior density and/or energy content to conventional liquid organic fuels. These hybrid organic fuels used in combination with metal particle afford fuels with 5 to 80% more net heat of combustion (based on volume). These fuels should extend the distant range for jets, liquid rocket engines, SCRAM jet engines, and improve energy content in fuel-air explosive applications such as fuel-air explosives and in the Multi-Effects Weapons System (MEWS) where the fuel is used both for propulsion and explosive effects.

Abstract: Fine aluminum powders are prepared by decomposing alane-adducts in organic solvents under an inert atmosphere to provide highly uniform particles and believed particularly effective as fuels and additives, in pyrotechnics, and in energetic materials. Effective adduct species are trialkyl amines and tetramethylethylenediamine, ethers and other aromatic amines. Effective production is obtained at atmospheric pressure and at temperatures as low as 50° C. with xylene solvent. Toluene, dioxane, and tetramethylethylenediamine were also effective solvents. Aliphatic solvents and other aromatic and polar solvents are believed effective. Titanium catalyst was provided as a halide, amide, and alkoxide; and it is believed that the corresponding compounds of zirconium, hafnium, vanadium, niobium, and tantalum are effective as catalysts. Particle size was controlled by varying catalyst concentration and by varying the concentration of an adducting species.

Tertiarybutylbis-(dimethylamino)phosphine is prepared by reacting a phosphorus trihalide, PX.sub.3, with the tertiarybutyl Grignard reagent ((CH.sub.3).sub.3 C)MgX. The resultant product is treated with lithium dimethylamide reagent LiN(CH.sub.3).sub.2. Tertiarybutylbis-(dimethylamino)phosphine is then recovered from the reaction mixture. Phosphorus-containing semiconductor materials are formed by chemical vapor deposition by means of bubbling a carrier gas through the new compound and then transporting the ((CH.sub.3).sub.3 C)((CH.sub.3).sub.2 N).sub.2 P with the carrier gas to a heated substrate. Additional elements from groups II, III, V, and VI of the periodic table are then deposited on the substrate to form the Phosphorus-containing semiconductor materials.
