초록

A method is disclosed for preparing metastable nanoenergetic composites (MNC) and for wet loading those MNCs into percussion primer cups. The method involves dispersing nanosize reactants in an inert liquid or, alternatively, making a nanosize reactant surface modification for improvement of reactant's chemical inertness towards water, followed by application of additives supporting a solid reactant particle dispersion in water or water solution prior to mixing. After mixing of the reactants, one maintains the presence of liquid water together within an ...

청구항

We claim: 1. A method for preparing a primary percussion primer containing a metastable nanoenergetic composite as a primary explosive ingredient where the metastable nanoenergetic composite is a sole explosive ingredient in the percussion primer, comprising: mixing a hydrophilic protective reagent with an oxide-passivated aluminum nanopowder for coating a surface of said oxide-passivated aluminum nanopowder for forming a protected surface coated oxide-passivated aluminum nanopowder, wherein the hydrophilic protective reagent is selected from at least o...
