    摘要: A non-toxic, non-hydroscopic percussion primer composition and methods of preparing the same, including at least one explosive component that has been traditionally considered a moderately insensitive explosive or secondary explosive, and at least fuel particle component having a particle size of about 1.5 microns to about 12 microns, which allows the use of moderately active metal oxidizers. The sensitivity of the primer composition is created by the interaction between the moderately insensitive explosive and the fuel agent such that traditional primary explosives such as lead styphnate or DDNP are not needed. The primer composition also eliminates the risks and dangers associated with traditional nano-sized fuel particles.

    摘要: This melt-pourable explosive composition shares explosive properties comparable to those of Tritonal and is melt-pourable and castable under conditions comparable to those of Tritonal, but experiences equal or less impact, shock, and thermal sensitivity and avoids the issues of toxicity associated with trinitrotoluene. The trinitrotoluene component of Tritonal is replaced with one or more mononitro aromatic and/or dinitro aromatic melt-pourable binders, such as dinitroanisole, which can be melt poured without presenting the toxicity drawbacks experienced with the use of TNT. The melt-pourable binder can also be combined with a processing aid selected from the group consisting of alkylnitroanilines and arylnitroanilines. The composition also includes oxidizer particles, which are preferably inorganic oxidizer particles, and a reactive metallic fuel, such as aluminum.

    摘要: A nitrate or nitroparaffin-base liquid exlosive composition having a small critical diameter yet which is essentially free of particulate metals such as may render such compositions unduly brisant or susceptible to decomposition, and which is consistent with the safety requirements of geological fracturing, including an inert solid ballistic modifier having a sonic velocity substantially different from that of the explosive material in the composition and an average particle size of less than 10 microns, forming from about 5% to 20% by weight of the composition.

    摘要: This invention involves the incorporation of a relatively small quantity ofirconium or other pyrophoric material in the high explosive composition of a munition, which provides incendiary, terrain illumination, spotting, and enhanced antipersonnel properties to the munition with little or no diminution of its explosive and fragmentation power.
