Abstract
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—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.
