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

An explosive composition comprises a porous fuel and an oxidizer. The porous fuel is a solid with a structure size measuring between about 2 nm and 1000 nm and has a porosity that lies between 10% and 98%. The oxidizer is solid or liquid at room temperature and is incorporated into the pores of the porous fuel. The oxidizer is selected, in an amount of at least 50% by weight relative to a total quantity of the oxidizer, from the group consisting of hydrogen peroxide, hydroxyl ammonium nitrate, organic nitro compounds or nitrates, alkali metal nitrates or earth alkali metal nitrates as well as metal nitrites, metal chlorates, metal perchlorates, metal bromates, metal iodates, metal oxides, metal peroxides, ammonium perchlorate, ammonium nitrate and mixtures thereof.

Explosive composition and its use

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.
