A multimodal explosive, in particular for blast charges, which has, for increasing the power, a powder additive which is formed by a hydrogen-terminated monocrystalline silicon powder of at least one grain size range, which powder has the advantage that no oxidation phenomenon takes place even over many years&#x2014;even at storage in ambient air. Due to the non-oxidized crystal surfaces, advantageously an immediate joint reaction with the explosive takes place in the detonation front and also extends into the post-reaction period with increasing crystal sizes, so that a different propellant effect is achieved depending on the additive.

Multimodal explosive

Insensitive explosive molding powders are provided that include an explosive component, a binder and a plasticizer. The insensitive molding powders include explosive crystals that are bound by a binder system. Moreover, the insensitive high explosive molding powder of the present invention has a bi-/tri-/tetramodal grain composition comprising coarse grain (280-360 &#x3bc;m with an upper limit of 500-700 &#x3bc;m) and fine grain (e.g., 35-45 &#x3bc;m) explosive crystals that a bonded by a binder system comprising a plasticizer and a binder. The molding powder of the present invention is coated in waterless solvent process having a solvent content of less than 0.01 wt. % and is immediately ready for pellet pressing.

In a nanostructured reactive substance and a process for producing the same, intermixing of silicon and oxidizing agent on a nanometer size scale permits virtually direct contact between the fuel and the oxidizing agent, only separated by a barrier layer. After the barrier layer is broken open, fuel and oxidizing agent are spatially directly together and can react, liberating energy. The reactive substance has a high reaction rate in comparison with conventional reactive materials.

Nanostructured reactive substance and process for producing the same

An electrical igniter cap has a reproducible igniter characteristic by virtue of the fact that, at the firing side, an igniter unit is covered by a sheeting of plastic material which is rupture-resistant but tears quickly, and also at the firing side it bears against a sieve plate with defined hole cross-sections.
