Definitions
- the invention relates to an explosive according to the preamble of claim 1.
- nanostructured porous reactive substances consist of reactive bodies whose voids are in the size range of 1 to 1000 nm, which are provided with oxidizing agents.
- the reactive substances consist of mutually independent, protective-layer-coated reactive ones
- Particles There is also described a process for producing such reactive substances, wherein nm-sized fuel particles having 1 to 1000 nm-sized interstices, first by annealing at 20 to 1000 ° C in air or by chemical or electrochemical processes or by vapor deposition with a protective layer and then the interspaces are provided with an oxidizing agent.
- the fuel particles provided with the protective layer and the oxidizing agent can be pressed into a reactive body.
- the fuel particles may consist of silicon, boron, titanium or zirconium.
- the invention has for its object to provide an explosive, especially for Blastladungen, of the aforementioned type, which has an improved blast behavior above and below water.
- Silicon Single Crystal Powders also shows no signs of oxidation for years. This is true even when storing silicon nanopowders in ambient air. Silicon single crystal powders have almost the same heat of combustion and reactivity as pure aluminum powder, ie non-oxidized aluminum powder.
- hydrogen-passivated silicon powder is a significantly more interesting additive than the aluminum powder used in secondary explosive mixtures, since an immediate co-reaction takes place in the detonation front as a result of the non-oxidized crystal surfaces of the silicon powder, which also extends into the after-reaction period with increasing crystal sizes. It is so with increasing crystal sizes a so-called sliding effect, d. H. achieved a temporal extension of the detonation pressure pulse. For example, with long-term stable d. H. unoxidized silicon powder having a particle size of about 1 .mu.m during the Explosengstoffumsetzu ⁇ g achieved an immediate significant contribution to the detonation front and when using a coarse grain of z. B. 350 microns achieved an additional post-reaction and thus a sliding effect.
- the explosive according to the invention in particular for Blastladungen, which has a hydrogen-passivated addition of silicon powder to secondary explosives to increase performance, which is formed of silicon single crystal powder, for example, starting with a grain size of 350 microns (average) of the first particle size range of the silicon single crystal powder of silicon Single crystal powder may be formed, which has a grain size of about 1 micron - 8 microns, and it may be the second grain size range of the silicon single crystal powder at about 40 microns and in the third range of 200 to 500 microns, preferably from about 350 microns, namely after application only one Grain size range or a mixture of the aforementioned fractions.
- the proportion of silicon single crystal powder may be 15-55 wt.%.
